摘 要:曹村矿11#煤层顶板节理发育、承压性差,并且综采顺槽及切眼断面较大,11#煤层顶板的支护问题已成为掘进技术的难点。传统的支护形式为梯形工字钢棚,掘进速度慢,劳动强度大,且顶板难控制,回采时端头难以维护,工序复杂,安全性差。为此,采用锚网梁索联合支护工艺,获得了大断面支护的相关参数,取得了成功。为安全生产创造了良好的工作环境,减轻了劳动强度,提高了效率。11# coal seam roof joint growth and bearing pressure is poor in Caocun coal mine, also the crossheading of fully mechanized mining coal and the cross section of open - off cut is large, the supporting problem of 11 coal seam roof becomes the difficulty of the tunneling technology. The traditional supporting form is the trapezoidal girder steel shed, the tunneling speed is slow, the labor intensity is big, and the control of roof is difficult, when stopping the end supporting maintains bolting mesh and beam -rope tion support, get the success. sity, raises the efficiency. difficultly, combined Creats the the working procedure is complex, the supporting technology, has obtained the good working conditions for the safety in security is bad. Therefore, uses the related parameters of large cross sec- production, reduces the labor intensity, raises the efficiency.
