蒋庄煤矿16煤层矿井涌水量预计探讨
|
摘要
蒋庄煤矿的主采煤层将由开采3煤层逐渐变为16煤层。为了合理设置和调整矿井排水系统,更好地开展16煤层矿井防治水工作,尽可能准确地预计矿井涌水量。矿井16煤层已开采了多年,其矿井涌水规律需要根据近几年的资料进行总结和研究,对涌水量进行预计。简要分析了蒋庄煤矿矿井水文地质条件,结合矿井实际,对16煤层充水因素进行了分析,确定开采16煤层主要充水水源为十下灰含水层。在此基础上对16煤层涌水量进行了预计,并对预计结果进行了评价。该文分别采用大井法、比拟法和趋势线预测法等3种方法对矿井涌水量进行了预计,其中对传统的大井法进行了改进,并创造性地运用了趋势线预测法,并对各种方法的可靠程度进行了评价,对各种方法预计结果进行比较,在此基础上确定预计的矿井涌水量,从而使得预计的结果更加科学、合理,为下一步矿井防治水工作提供了可靠的依据。
Major coal mining layer of Jiangzhuang coal mine is chaning from No.3 coal layer to No.16 coal layer. In order to reasonably set and adjust mine drainage system of No,16 coal layer,carry out water prevention and control work,mine water gushing should be predicted accurately as much as possible. No.16 coal layer has been explored for many years. The rule of mine gushing water should be summarized and studied based on the data in recent years,and the gushing water is predicted. In this paper,hydrogeological conditions of Jiangzhuang coal mine has been briefly analyzed. Combining with actual condition of the mine,filling water source of No. 16 coal layer has been analyzed. It is determined that main water source in No.16 coal layer is water-bearing layer of the lower part of No.10 ash aquifer. On these basis,water inflow of No.16 coal layer is predicted,and the prediction result is evaluated. By using large well method,comparison method and trend line prediction method,mine water discharge has been predicted. Traditional well method is improved and the trend line prediction method is used creatively. On this basis,the expected mine water discharge quantity is determined,which makes the forecast result more scientific and reasonable,which provides a reliable basis for the next work of mine prevention and control.
