Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1888 edition. Excerpt: ...along the gangway. This opening is the heading--here--and is usually 4 to 6 feet wide and 6 feet high. From this are opened up the breasts or rooms in which the real mining is done. But as the coal mined is to go to the cars in the gangway--sliding down, as I have stated--there must be openings, corresponding with each breast, made in the strip of coal between the gangway and heading, through which the loose coal can pass. These openings are called shutes, and are made 4 to 6 feet wide and 4 feet high. Here they are, these narrow openings which connect the gangway and heading, and in some of which I have made an S--for shute. By means of a platform built in the lower end of the shute, to a height equal to that of the mine cars, the coal slides down the shute and drops into the car standing on the gangway track. In very steep-dipping beds, the loose coal comes tumbling down at a great rate, while in those where the dip is comparatively slight, it must be pushed along. These shutes divide the strip of coal left standing into a number of blocks, as you see; these are the gangway stumps--the same as you saw yet standing in the first lift. I was not careful, enough, I notice, in making my picture. Some of the shutes appear wider than others, and the same is true of the stumps, as also of some of the other openings and pillars. We can correct this in our minds, however. Now for the breasts--the real mining places. These white spaces above the heading represent the breasts, the black strips between being the pillars left standing to support the roof. Breasts are commonly about 8 yards wide, but sometimes, are made 12 yards wide--the width varying in different mines, depending upon the nature, to some extent, of the roof. The pillars between the breasts...show more
