摘要
为了保证综采工作面的安全生产,针对煤层赋存情况,进行了回采巷道支护参数选择、制定了采煤机合理的进刀和割煤方式;根据顶板情况,确定了适合顶板管理的移架方式和端头支护形式及超前支护距离,确保了回采工作的安全高效。
In order to ensure the safety of fully mechanized working face production,in view of the occurrence of coal seam,the mining roadway supporting parameters selection,formulate the reasonable way of feed and cutting coal shearer;According to roof condition,determined the suitable way of moving frame and roof management end supporting form and lead supporting distance,ensure the safety of recovery working efficiency.
