摘要
本文综合分析了韩家洼煤矿22#、25#煤层的水文地质条件,详细分析了影响22#、25#煤层的含水层、隔水层的性质,系统整理了韩家洼煤矿的充水条件,利用工程类比、理论计算以及现场实测的方法对矿井涌水量进行了计算,综合多方面考量,认为韩家洼煤矿22#、25#煤层水文地质类型综合评定为中等类型。并在此基础之上,提出了一系列针对韩家洼煤矿生产实际防治水措施,达到了良好的效果。为水文地质条件类似的矿井提供了科学的参考方法。
This paper comprehensively analyzes the hydrogeological of 22# and 25# coal seams in Hanjiawa Coal Mine, analyzes the nature of aquifers and aquicludes of 22# and 25# coal seams in detail, and systematically refines the water filling conditions of Hanjiawa Coal Mine. The calculation of mine water inflow is carried out by engineering analogy, theoretical calculation and on-site measurement. Based on various considerations, it is considered that the hydrogeological types of 22# and 25# coal seams in Hanjiawa Coal Mine are comprehensively classified as medium type. Based on this, a series of measures for actual water prevention and control in the Hanjiawa coal mine were put forward, which achieved good results. It provides a scientific reference method of water control for coal mines which hydrogeological type are similar to hanjiawa.
