口孜东矿西翼大巷优化设计

摘要

口孜东矿开拓巷道主要支护方式为一次锚网索喷支护加二次套棚支护，由于受深井地压的影响，深井支护难题很长一段时间都没能得到有效解决，部分巷道变形严重，制约了安全生产。通过实践经验教训，对支护方式进行优化，采用一次加强锚网索喷联合支护加拱部以上部位二次锚网喷支护及注浆加固支护方式，取得良好效果。%The support method of KuZiDong mine roadway support is bolt mesh spray and anchor in ifrst, the shed supporting is as the second support, because of the inlfuence of the deep pressure of deep mine, the support problem can’t be solved effectively for a long time, part of the roadway deformation is serious, which restrictes the safe production. Through the experience and lessons, optimized the supporting method, using the combined supporting that the bolt mesh spray and anchor is as the ifrst support , the anchor net spray support and grouting is as the second reinforcement method, which achieved good supporting effect.
