长沟峪煤矿矿井涌水规律数值模拟研究
|
摘要
长沟峪煤矿为急倾斜煤层开采矿井,其主要充水水源为大气降水。长期以来,长沟峪煤矿采用大井法预计矿井正常涌水量,采用含水系数法预计最大涌水量,事实证明这些方法无法保证长沟峪煤矿的安全生产。
本文以长沟峪煤矿为研究背景,在对其水文地质条件进行综合分析的基础上建立相应的地下水运动数学模型,考虑不同雨强、雨时、开挖扰动对研究区域的影响,运用GeoStudio软件对矿井涌水变化规律进行数值模拟,得到结论如下:雨水主要通过上覆破坏岩体和地表塌陷坑汇入井下;降雨强度接近井田入渗能力的雨型,持续时间越长,对矿井造成的影响就越大;随着开挖活动的进行,矿井涌水量开始增加,同时渗流速度也有所加快。在此基础上为长沟峪煤矿提出了矿井水防治建议。
Changgouyu coal mine is urgent incline coal seam mine and the main water source is rainfall. Changgouyu coal mine uses big well method to predict nomal water inrush and uses aquifer coefficient to predict max water inrush for a long time. Fact proves that these methods is not able to ensure the safe production of coal mine.
The article chooses changgouyu coal mine for background and establishes mathematical model of groundwater movement based on hydro-geological conditions.And then the article uses GeoStudio software to simulate the varying water inrush law considering the impact of rainfall intensity、rainfall duration、excavation disturbance to the study area, conclusions are as follows: rain goes mainly into working face through the overlying rock surface and collapse; the duration of rainfall whose intensity is closer to the infiltration capacity of coal mine is longer,the impact is worse; excavation makes the volume of water inrush more and more and speed of water inrush faster . At the last the article provides advices to prevent mine water based on the study.
