摘要:
为了探究其水害成因、涌水规律，并找到合适的水害防治手段，采用工业分析、煤岩组分、元素分析等微观实验手段，分析柳塔煤矿各煤层煤体的含水分布及微观影响因素并结合矿井煤系地层赋存特征、区域降水特征、井下涌水统计数据，对柳塔煤矿煤层的涌水来源、涌水构成、涌水的影响因素及其对瓦斯赋存的影响进行分析。结果表明，柳塔煤矿富水性较差，且水分随深度逐渐增加；采动形成的大量裂隙使得原有的隔水层产生裂隙，形成了涌水通道；矿井的涌水量与降水量密切相关，应加强顶板水害的防治。
Abstract:
Liuta coal mine is characterized by the complicated geological conditions of typical composite waterresisting layer with multiple coal seams interaction,and in recent years,the amount of underground water inflow presented the increasing trend,which significantly affected the safe and efficient mining of coal mine.In order to explore the causes of water disaster and the laws of water inflow,and find out the suitable prevention and control methods of water disaster,the water content distribution of coal body in each coal seam of Liuta coal mine and the micro influencing factors were analyzed by using the micro experimental methods of industrial analysis experiment,coal and rock composition experiment,and elemental analysis experiment.Combined with the occurrence characteristics of coal measure strata,regional precipitation characteristics and statistical data of underground water inflow of the mine,the source,composition and influencing factors of water inflow in the coal seam of Liuta coal mine and their influence on the gas occurrence were analyzed.The results showed that the water abundance of Liuta coal mine was poor,and the water content increases gradually with the mining depth.A lot of fractures induced by the mining made the original water-resisting layers generate the fractures,which formed the water inflow channels.The water inflow amount of mine was closely related to the amount of precipitation,and the prevention and control of roof water disaster should be enhanced.
