在采准巷道中矿山压力的剧烈显现是深部矿井的主要特点之一。在塔列赞特拉兹特生产联合体的“进步”矿,开采埋藏深度为900～120m的h_8煤层,在采准巷道中矿山压力主要出现在工作面后方回采工作影响带中。 该矿与莫斯科矿业学院一起共同完成了用切顶钻孔进行顶板内部爆破工作,以确定它对支承压力显现的影响。实验和观测工作在南盘区西工边缘人 One of the main features of deep mines is the dramatic appearance of pressure in the quarry. At the “Progressive” mine at the Consortium of Tarzantetrazeter, the h_8 coal seam with a buried depth of 900 to 120 m was drilled. The pressure of the mine mainly appears in the impact zone of the back-mining work behind the working face in the quasi-entry roadway. Together with the Moscow Institute of Mining, the mine completed the roof blasting with top-cut drilling to determine its effect on the bearing pressure. Experimental and observational work is on the margin of western workers in Nanpan District
