摘要
针对石炭系8#层沿空留巷切巷掘进时,受大断面、沿空留巷切顶卸压及开采时周期来压等因素作用下,邻面切巷会出现底鼓、顶板下沉、煤帮变形等矿压显现问题,采用“先同后异平齐法”掘进工艺,实现了安全、快速掘进,并在晋能控股煤业集团同忻煤矿C8#层8105工作面得到应用,创经济效益10万元左右。
In response to the influence of factors such as large cross-section,roof cutting and pressure relief along goaf,and periodic pressure during the excavation of No.8 Coal Seam of Carboniferous,which may lead to the occurrence of mining pressure phenomena such as bottom bulge,roof subsidence,and coal wall deformation in adjacent working faces,the"same before different leveling"excavation process is adopted to achieve safe and rapid excavation,And it has been applied in the 8105 working face of No.8 Coal Seam of Carboniferous at Jinneng Coal Industry Group Tongxin Coal Mine,creating an economic benefit of about 100000 yuan.
