摘要:
在分析黄陵一号煤矿水文地质条件与充水因素的基础上,认为直罗组下段含水层是2号煤层顶板涌(突)水的主要水源。通过经验公式计算与实测冒落带和裂隙带(简称“两带”)高度的对比分析,认为经验公式不适合该区开采实际,适合该区的冒采比和裂采比分别为5.7和25.2.以裂采比32为阈值,对矿井中北部2号煤层待采区进行了顶板涌(突)水危险性分区预测,为矿井防治顶板水害提供了依据。
Abstract:
Based on analyzing the hydrogeological conditions and the water filling factors of Huangling No.1 mine, it is considered that sandstone aquifer of the lower Zhilo Formation is main water source for water inflow(inrush)of No.2 coal seam roof. A comparative analysis of the heights of caving zone and fractured zone(“two zones” for short)by empirical formula and measured value, we conclude that the empirical formula disagree with the mining practice in this area, and determine the caving/mining height and fractured/mining height is 5.7 and 25.2, respectively,for this area. With the ratio of fractured/mining 32, partitioning prediction of the risk of roof water inflow(inrush)at coal seam No.2 in the north centre of the mine field is completed to provide basis for mine water hazard control.
