摘要：
Some of the topics discussed are the following: the necessity for the rational concentrated production of coal mine shafts (dispersed production, high mine density, high rate of maintenance of mine roadways, and low labor productivity); and principal technological methods for the concentrated production of mine shafts, such as by concentrating the working fact with the use of mechanized mining and the lengthening of the working face, as well as by other measures.
