摘要
三交河矿2-2煤层为近距离煤层开采范畴,2-2煤层顶板层间距为0.8~4.5 m;为保证矿井的正常衔接,解决近距离煤层大断面切巷支护难题,矿井在2-2-603工作面进行刷扩安装同步施工技术应用实践;安装工期短,节约了支护成本,降低了施工强度,达到了预期的安装效果。
The 2^-2 coal seam in Sanjiaohe Colliery is close distance coal seam mining, and the spacing of the 2^-2 coal seam roof layer is 0.8～4.5 m. In order to guarantee the normal connection of mines and solve the support problem in cutting roadway of large section in close distance coal seam, brush installation synchronous construction technology has been applied in 2^-2-603 face,which saves supporting cost, reduces construction strength and achieves expected installation results.
