摘要
为了加强双侧采空下沿空留设巷道的顶板稳定性,避免沿空巷道的顶板在回采扰动作用下出现破碎垮塌事故,通过对某矿综采工作面沿空留巷原有支护设计稳定性进行研究分析,并进行优化设计。经现场实际应用发现,取得良好的效果。
In order to strengthen the stability of the roof of the gob side entry under both sides of the gob and avoid the collapse accident of the roof of the gob side entry under the mining disturbance,through the research and analysis of the stability of the original support design of the gob side entry in a fully mechanized mining face,and the optimization design,it is found that good application results have been achieved through on-site practical application.
