综采放顶煤开采难点技术的研究与探讨

The Difficult Technical Problems of Fully-mechanized Caving Mining

综采放顶煤技术受煤层赋存条件、回采工艺等制约,特别在煤层倾角大的情况下,造成工作溜子、支架上窜下滑,倒架咬架的机率增加,机组电缆容易甩入运行的工作溜子当中,造成机电事故。就矿压显现规律的监测与分析、大倾角综采放顶煤技术生产工艺、三机配套以及端头支架的使用进行了研究与探讨。

Fully -mechanized cving mining is restricted by coal deposite and mining technique , So that it is easy to induce various accident mining angle. This paper disscussed monitoring strata behaviors, mining technique under large inclired angel and setting equipments.
