To quickly assess the difficulty of the text, read a short excerpt:
The surveyor is frequently called upon to establish a drain- age system for a mine. In flat seams, he must then, if he has not already done so, run a line of levels and determine the proper points at which to establish small sumps from which the mine water shall be conducted to the main sump. Some- times it is possible to drain all the water into the old workings. A complete map of old workings is necessary in order that the volume of water that can be stored may be determined. AND THEIR APPLIC...ATIONS TO MINING ENGINEERING ji Dams should then be placed where they may have good pillars to hold them in place. Several of the large coal companies carry all water in ditches in the back entries. Some of the Michigan copper companies handle all the mine water through one shaft. This necessitates that there be an opening con- necting the mines so that water can run freely from any point to the drainage shaft. Recently at Cripple Creek a tunnel has been driven in order to drain a number of mines.
