摘要
通过在同家梁矿14#层311盘区51013巷与311-1巷交汇处架设20#工字钢钢架做交叉点对顶板进行加强支护,保证了上覆煤柱下巷道支护的稳定性,促进了矿井的安全生产,对类似顶板条件的巷道支护技术具有一定的借鉴意义。
In this article, we erected on the 20th I-beam steel frame at the intersection point of 14 coal seam, 31 ldistrict, 51013 roadway and 311-1 roadway in Tongjialiang mine. Through this method, we reinforced the roof support at this point and adopted a safe, efficient, reasonable support pattern, so that it ensured the integrity and stability of roadway support under the overlying coal pillar. Besides, it also promoted the safe production of mine. It has certain referential significance to the roadway supporting technology at similar roof conditions.
