通过对井田内水文地质条件及可采煤层赋存情况的分析,对井田内含水层和隔水层进行了划分,并对各主要含、隔水层(组、段)的岩性、厚度、埋藏条件、分布规律及水位、水质、富水性和补给、径流、排泄条件及各含水层(组、段)之间的水力联系进行了详细阐述。分析研究了矿井的充水因素,指出在留设防水(砂)煤岩柱条件下,开采3～10煤层时,新生界第四含水层(组)为间接充水含水层,直接充水水源为二叠系主采煤层顶底板砂岩裂隙水;开采10煤层时,正常情况下太原组1灰距10煤底板较远,对开采10煤层无直接影响,但在由断层作用导致断层间距缩短或对口的部位有突水危险。此结果为矿井今后煤层开采过程中降低水害威胁、制定防治水对策提供了帮助。
Based on the analysis of the hydrogeological conditions and the occurrence of coal seams in the minefield, the aquifer and aquifuge in the minefield are divided. The lithology, Thickness, burial conditions, distribution rules and water level, water quality, water-rich and recharge, runoff and discharge conditions and the aquifer (group, section) between the hydraulic connections were described in detail. Analyzed and researched the water filling factor of mine, pointed out that under the condition of leaving waterproof (sand) coal pillar, the fourth aquifer (group) in the Cenozoic is an indirect water-filled aquifer when mining 3 ~ 10 coal seam. Permian main coal seam roof and floor sandstone fissure water; mining 10 seam, under normal circumstances Taiyuan Formation 1 10 meters away from the floor of the coal floor, no direct impact on mining 10 seam, but in the fault caused by the fault interval or There is a danger of water bursting at the mouth of the mouth. This result has helped to reduce the threat of water hazards and formulate water control measures in the coal seam mining in the future.
