摘要
正确预计老空区积水量是煤矿安全探放老空水的前提条件。通过对积水空间法理论公式的分析与完善,利用1331(3)上顺槽探放老空水的实际资料对13_(-1)煤层采空区充水系数进行研究,总结出谢桥矿13_(-1)煤层采空区充水系数的经验数据,并经现场验证效果良好,也为今后老空水量预计过程中相关参数的选择提供了更加合理、科学的参考依据。
The safety of explorating and discharging goal water is on the premise of the amount ot goat water that correctly predicted. Analysised and improved the theoretical formula of the water space method, and the impvoed method has been made a very good application in the actual process. Through site verification, got empirical data of water filling coefficient from the goaf of No. 13-1 coal sea in Xieqiao mine,which could provide a more reasonable and scientific reference in predicting the amount of goal water.
