| 摘 要： | 本文从放顶煤开采的一次采高大、上覆岩层的活动范围大、破碎顶煤的存在等基本特征出发,论述了关于放顶煤开采中瓦斯、顶板和冲击地压等安全问题.放顶煤开采对有些安全问题可以缓解,比如工作面的瓦斯突出.但是也可能诱发一些安全问题,如坚硬顶板对支架的冲击、采空区垮落岩石的撞击与摩擦诱发瓦斯事故等.在放顶煤大面积推广应用的同时,更应重视其相应的安全问题的系统研究与解决.

| Abstract: | There are some basic characteristics such as the high mining height, the large strata disturbed on the coal seam and the broken top coal in the longwall top coal caving. Based on these characteristics, this paper discusses the gas, roof rock and shocking mining pressure etc. of the longwall. The longwall may relax some safety problems, but the other safety problems such as hard roof rock, the colliding and friction of the caved rock each other may be induced or intensified. The safety problem should be paid greater attention in the using the longwall. |
