摘要
通过使用ZF-4600轻型放顶煤支架过煤柱的实践和压力显现分析,认为使用网下放煤支架虽然支撑能力低于ZPL-600型支架,但只要措施到位,方法正确,仍能安全过上分层煤柱进行开采,可创造出较高的经济效益。
Through practice and researching the law of strata pressure behavior during the application of light roof caving support, the paper thinks that although the support force of sublevel caving supporter is less than ZF-4600 supporter, it is safe coal mining passing through pillar in top slicing seam and can create higher economic efficiency as long as properly measures and method is in place.
