摘要
该文介绍了龙煤鹤岗分公司新岭煤矿通过采用沿空留巷技术对复采区进行开采,有效地解决了采掘接续紧张的难题。沿空留巷技术具有煤炭回收率高、回采工作面衔接合理、巷道掘进率低、掘进排矸少等优点,尤其是煤巷掘进速度仅为80～100 m/月的复采煤层,采用沿空留巷技术效果更好。
That paper introduce LongMei Minging Group co,. ltd HeGang sub - company XinLing Coal Mine adopt the Technology of remained tunnel for continuous usage in worked - out area to mine in second mining panel, this technology solves the problem of Mining splice tension and it includes many advantages, such as： High coal recovery rate, working face reasonable convergence, low efficiency of roadway excavation,less driving discharge refuse, espe- cially in the second mining coal seam that the roadway tunneling advance rate is 80 - 100 metre per month get a good efficiency.
