新密市煤矿区隐蔽致灾因素分析及预测

Analysis and prediction of hidden disaster causing factors in Xinmi City's coal mines

煤炭是我国的主体能源,煤矿安全生产关系着煤炭工业的持续发展和国家能源安全,也关系着矿工的生命财产安全。针对新密市煤矿区历史上各矿井隐蔽致灾因素引发的矿井安全事故,总结出新密市煤矿区隐蔽致灾因素主要为矿井瓦斯及底板突水。通过研究煤矿区范围内瓦斯地质规律及水文地质特征,对区内主要隐蔽致灾因素进行分析及预测,有利于指导各矿井以后安全生产。

Coal is the principal energy of China.The safety production of coal mines is concerned with the sustainable development of coal industry and energy safety of China,as well as the life and property security of coal miners.Through an analysis of Xinmi City′s past mine safety accidents that were caused by hidden disaster causing factors,it was summarized that the safety accidents are mainly caused by mine gas and water inrush from the coal floor.By investigating the geological regularity and hydrogeological features in the coal mine areas,the author made a detailed analysis and prediction of main disaster-inducing factors,which is beneficial to guide all coal mines and their safety production.
