矿井中组煤顶板分析及安全管理措施研究

Analysis of coal roof in coal group and study on safety management measures

本文以大桥沟煤业中组煤开采为研究背景,通过对矿井顶板岩性进行分析,中组9、10、11号煤层工程地质条件类型为差~中等,顶板垮落性较好。提出了工作面回采相应的安全管理措施,为同类型矿井安全回采提供借鉴意义。

In this paper, Daqiao Gou coal mining group as the research background, through the analysis of the mine roof lithology, the engineering geological conditions of No.9, No.10 and No.11 coal seams in the middle group are poor to medium, the roof caving is good. The corresponding safety management measures of working face mining are put forward to provide reference for the safety mining of the same type of mine.
