摘要
针对中厚煤层开采后回风巷矿山压力显现明显的问题,打通一矿W2807工作面采用沿边掘巷技术,解决了中厚煤层回采过程中受回风巷道断面小、通风困难、巷道变形、底鼓等因素的影响,从而达到高产高效的开采目的。
Aiming at the obvious problems of mine pressure in return air roadway after mining in medium and thick coal seam, W2807 face of No. 1 Coal Mine adopts side excavation technology, which solves the problem of small cross section, difficult ventilation and deformation of roadway during mining process of medium thick coal seam. Bottom drum and other factors, so as to achieve high-yield and efficient mining purposes.
