摘要
分析了韩家湾煤矿浅埋煤层开采支架的适应性,总结了厚松散层覆盖层浅埋煤层综采工作面的矿压显现规律。同时针对目前顶板的支护状况和顶板灾害危险,提出了提高支架初撑力等改进措施,为实现厚松散层覆盖浅埋煤层综采工作面安全开采提供了依据。
With the adaptability of the supports used in shallow coal seams in Hanjiawan Coal Mine analyzed,this paper makes a study of the strata behaviors regularity in the longwall faces under thick and loose overlying strata.Besides,in line with the current support status and dangers of roof related hazards,this paper proposes to increase the setting load of the supports,thus providing reliable grounds for improved safety in mining in the longwall faces under thick and loose overlying strata.
