葫芦素煤矿冲击地压灾害综合评价

HuLuSu coal mine impact geostatic pressure disaster quality synthetic evaluation

葫芦素煤矿主采煤层埋藏深度600~900 m,随着开采深度的不断增加,生产条件、地质因素的变化导致煤层开采冲击危险性发生很大变化。采用模糊综合评价方法对影响地层冲击地压灾害的各项因素进行综合评估,确定葫芦素煤矿地层冲击地压危险等级,同时根据矿井现有条件,从技术和管理两方面制定冲击地压的防治措施,确保矿井建设和生产安全。

The buried depth of main coal seam of Hulusu Coal Mine is 600 to 900 m.With the continuous increase of mining depth,because of the changes in production conditions and geological factors,There is a great change in the impact risk.In this paper,using fuzzy comprehensive evaluation method,comprehensive assessment of various factors affecting ground pressure disasters was carried out,The hazard grade of ground pressure in the gouru coal mine is determined.At the same time,according to the existing conditions of mine,From the two aspects of technology and management,the prevention and control measures of rockburst are made,to ensure the safety of the mine construction and production.
