摘要
为了研究庙哈孤矿区浅埋煤层开采导水覆岩裂隙带发育规律,以安山煤矿133103工作面为研究背景,采用理论分析与现场实测相结合的手段对3-1煤层开采后覆岩裂隙发育规律进行研究。结果表明,133103工作面垮落带高度10.69~15.88 m,垮采比为4.86~5.73,导水裂隙带发育范围52.33~62.52 m,裂采比为23.8~28.4。研究成果为庙哈孤矿区类似条件下工作面开采顶板水灾害防治提供参考。

Abstract
In order to study the development law of water conduction overburden fracture zone in shallow coal seam mining in Miaohagu mining area, taking No.133103 Face of Anshan Mine as the research background, the development law of overburden fracture after No.3-1 coal seam mining was studied by means of theoretical analysis and field measurement. The results showed that the caving zone height of No.133103 Face was 10.69 ~ 15.88 m, the caving ratio was 4.86 ~ 5.73, the development range of water conduction fracture zone was 52.33 ~ 62.52 m, and the cracking ratio was 23.8 ~ 28.4. The research results provided a reference for the prevention and control of roof water disasters in working face mining under similar conditions in Miaohagu mining area.
