摘要
郑州地区登封煤田、新密煤田、荥巩煤田(巩义行政区除外)煤矿开采时间长,小煤矿数量曾经超过1 000个,兼并重组以来,大批小煤矿关闭,但采空区、废弃井筒、不良钻孔等引发煤矿事故的隐蔽致灾地质因素普遍存在,同时还存在断层、褶曲等致灾地质因素。由于煤矿技术装备的落后,技术资料的欠缺,致灾因素不清楚,煤矿在开采过程中极易引发事故。利用数学公式分析的方法,预测各矿区导水裂隙带和瓦斯含量的变化趋势,从而对瓦斯、导水裂隙等主要致灾因素有了一个量化的分析。结合郑州地区煤矿实际情况,从整个郑州市辖区存在的煤矿隐蔽致灾因素进行剖析,同时系统分析郑州地区煤矿存在的主要隐蔽致灾地质因素,为郑州辖区煤矿制定灾害防范措施和方案提供依据。
Xinmi coalfield,Xinggong coalfield,Dengfeng coalfield(except the administrative region of the Gongyi) in Zhengzhou area have already had long time history of mining coal. There have been more than 1 000 small coal mines. A large number of small coal mines closed since the merger and reorganization,but the goaf,abandoned shaft,bad drilling etc are common. The hidden geological factors can cause coal mine accidents also exist,such as the faults and folds. Due to the backwardness of technical equipment and lack of technical data in coal mines,the cause of disaster is not clear,coal mines are prone to occur accidents during the mining process. Calculating the variation trend of water conducted and gas content by means of mathematical analysis in each mine area,quantitative analysis of the major hazard factors,such as gas and water conducted fractures,were obtained. Combines with the actual situation of Zhengzhou coal mining area,the paper analysed the hidden disaster factors of coal mine in the whole Zhengzhou District,at the same time,and systematically analyzed the main geological factors exist in the coal mines of Zhengzhou District,and provided reference basis for making disaster prevention measures and plans in coal mines of Zhengzhou.
