摘要
为了解决回风顺槽变形严重的问题,以沙坪煤矿W1319回风顺槽为研究背景,给出了锚杆、锚索为主,网、梁(钢带)为辅的联合支护方案。通过理论计算给出了锚杆、锚索的参数设定,通过现场实践,确定了支护的优越性,为矿井支护提供一定的参考。
In order to solve the problem of serious deformation of air return crossheading,taking W1319 air return crossheading of Shaping Coal Mine as the research background,this paper proposed the combined support scheme of anchor bolt and anchor cable as the main part and mesh and beam(steel belt)as auxiliary.Through theoretical calculation,the parameter setting of anchor bolt and anchor cable was given.Through field practice,the superiority of the support was determined,which provided certain reference for mine support.
