By fall of coal, By fall of rock, By mine wagons, Burned by gas, Total, Rolling Mill. This is the most extensive operation in the district and one of the best equipped; ventilation is produced by fan; haulage, by tail rope system, and the mining is conducted on the most improved plan the three heading system. In the pillar drawing considerable gas is given off, but the greatest of care is exercised to avert accidents from this source, as well as from all others usually met with in extensive mines. A mine foreman, an assistant, and two fire bosses are em ployed; also an Inspector over the hauling road and traveling ways, whose special duty it is to examine these ways, to keep everything safe and in good working order, and to make a written report to the superintendent once every week; said report gives the date when any danger is found, and when it was removed. To meet the wants of those who may be injured in or about the mine, two emergency boxes are kept at hand, one outside and one inside, each of which contains the following articles for immediate use: Soda, bandages, cotton gauze, adhesive plaster and small scissors. Following will be found the blank report which has been prepared by Mr. Morris, the superintendent of the mine, to be filled out each week by the inspector of the traveling or manway, as mentioned above. Mine foreman, David Edwards. BLANK REPORT. Cambria Iron Company Mining Department, Rolling Mill Mine. Weekly report of condition of the entire length of the manway. I made a personal examination of the entire length of the manway this Monday, 189 and find it in good and safe condition with the exception noted above. Approved. Inspector. Supt. of Mines. The repairs needed as shown by the above report, were completed this day of 189 . Inspector. Haw's Shaft.-I find this mine at all times in excellent order; ventilation, drainage, haulage and general safety are in the most satisfactory condition. Mine foreman, William Oppy. The Following Three Mines are Located on the Baltimore and Ohio Railroad. Krebs. Is located in Somerset county, near the town of Somerset. The ventilation and drainage of this mine are excellent; everything, in fact, necessary for the comfort and safety of the employes is carefully looked after by those in charge. Mine foreman, William McKee. Bethel. This is a small operation but is kept in splendid condition as regards ventilation and drainage. Mine foreman, Joseph Virgin. Ingleside. Is operated by the Ingleside Coal Company. The ventilation and drainage were in reasonably good condition when last examined. Mine foreman, William Moss. Argyle. This mine is always in good condition; its drainage, ventilation and general safety are well looked after. The ventilation is produced by a furnace, which is properly attended to; the hauling is done by machinery, the tail rope system having been adopted. Mine foreman, John W. Donaldson. Aurora. This mine was in good condition on my last examination. I measured 12,500 cubic feet of air in circulation, which was well distributed and conducted to the face of the workings. Mine foreman, Harry Gage. Euclid. A Stine fan was put in at this mine during the past year, which has greatly improved the ventilation. It can now be classed among the mines of the district having good ventilation and drainage. Mine foreman, Samuel Brewer. Conemaugh. This is not a very large mine, but it is one of the best ventilated in the district, the drainage is also excellent. Mine foreman, David Duncan. Stineman.-Is located at South Fork. At date of last visit to this mine, I measured 64,000 cubic feet of air in circulation. It was well distributed in the dip workings, but in the upper, or level workings I found some places a little defective, caused mostly by a creep upon that portion of the mine, which had partly closed up the airway which conducted the air to that division of the work. Shortly after my visit the foreman reported to me that another opening had been made, which remedied the defect in that part of the mine. The drainage is good. Mine foreman, R. Ott. Webster No. 3.-This is one of the largest operations in the district. It is practically two mines in one, as each of the two divisions (dip and level workings) has a separate haulage plant and each is ventilated independently of the other. Three fans are used to ventilate the workings, one large 18 foot fan for the levels and two 12 foot fans for the dip workings. Extensive improvements have been made here during the last year two Ingersoll air compressors having been erected and a hole drilled 365 feet deep and 10 inches in diameter, through which the water is to be pumped out of the dip workings by compressed air, instead of steam. Two incline planes are used to drop the coal down from the upper to the lower levels. On my last visit to this colliery I measured 90,000 cubic feet of air in circulation, 55,000 in the level and 35,000 in the dip which was well distributed through the workings. The drainage is also excellent. Mine foreman, James Callahan. Sumner No. 2.-This is an old mine and very difficult to keep in good condition; neither drainage nor ventilation is up to the standard. A new company and new officers have taken charge of the plant since the 1st of December; they contemplate remodeling it, and changing the system of mining entirely, which will, no doubt, improve the haulage, drainage and ventilation. Present mine foreman, John Daniel. Dunlo. This is a small operation, employing about thirty persons, but it is kept in excellent condition as regards ventilation and drainage. Mine foreman, Richard Pardoe. Yellow Run Shaft.-Is operated by the Berwind-White Coal Company. The ventilation is produced by a 16 foot fan. At date of last visit I measured 37,500 cubic feet of air in circulation; it was well distributed through the workings, and the drainage was improved since previous visit. A self-acting plane is now in operation, upon which the coal is dropped from the upper to the lower, or main level. Mine foreman, Thomas Booth. Henrietta Shaft.-A 12 foot fan was erected at this shaft during the year, which has greatly increased the ventilation. The drainage has also been improved during the past few months. The general safety of the mine and the sanitary condition was found to be very satisfactory on my last examination. Mine foreman, Thomas Williams. Puritan No. 1.-At date of last visit to this mine I measured 36,000 cubic feet of air in circulation, divided into four splits; in one of them I found the volume which was passing, too small to carry away the smoke made from blasting as fast as it should, and, therefore, suggested that two of the splits be united, to increase the volume passing per minute so that the smoke would be carried away faster from the men. The drainage is somewhat defective which is caused by the headings being driven too narrow to keep good ditches on the side; they are now increasing the width of the headings, which will be an improvement to the mine in ventilation, drainage and safety; especially for the drivers. Mine foreman, Harvey Mears. Puritan No. 2.-This is only a small operation opened along the boundary line of the Pilgrim mine and is ventilated by a split of air from the fan of that mine. When last examined I found a very good current of air in circulation through the workings; the drainage was also in fair condition. Mine foreman, George Bell. Ivy Ridge. This mine has been idle a great deal during the year, and was not in operation each time I made a visit in the vicinity during the later months. On my last examination it was undergoing a change in the system of ventilation, which I was fully convinced would greatly improve the sanitary condition of the mine when it should be completed. Mine foreman, Evan D. Davis. Pilgrim.-Extensive improvements have been made at this colliery during the year, electric haulage having been put in, in place of mules. This necessitated a great deal of change in the mine namely the widening of the headings, and the relaying of the tracks with heavier rails. The ventilation on my last visit was rather poor in one part of the mine which was caused by defective doors and stoppings which allowed the air to escape to the return before it reached that locality. The drainage is good, and there is no reason why the ventilation should not be the same, as there is a large volume of air forced into the mine by a 12 foot Guibal fan. I expect to find the defect remedied on my next visit. Mine foreman, Daniel Campbell. Sumner No. 1.—This mine is in excellent condition both as regards ventilation and drainage. There are three splits, each with volume enough to pass the air through the workings at a velocity sufficient to carry the smoke away quickly. Mine foreman, Joseph Appleyard. Excelsior. The drainage and ventilation of this mine on my last visit were very good. Mine foreman, Robert Pierce. Sonman No. 1.-The ventilation and drainage have been greatly improved here during the past year. Being an old colliery considerable difficulty has been encountered in bringing about the improvements. At date of last visit I found a brisk current of air passing through the face of the workings and good drainage throughout the mine. Mine foreman, Frank Morrison. Bens Creek Plane.-The ventilation and drainage here are not up to the standard. This mine was opened near an abandoned colliery and driven through a part of the old workings, which has destroyed the system of ventilation. It is only a small operation and has not a very large tract of coal to work on. Mine foreman, John Leap. Columbia No. 4.-When last examined, the condition as regards ventilation and drainage was fairly good. This mine is now driven in quite a distance, and will therefore require great care on the part |
