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。
Properly estimate the amount of water in the old empty area is a prerequisite for coal mine safety exploration of old empty water. Through the analysis and perfection of the theoretical formula of the water space method, this paper studied the water-filling coefficient of 13_ (- 1) coal seam gob area by using the actual data of 1331 (3) 13 _ (- 1) empirical data of coal-bed water filling coefficient, and verified by the field effect is good, but also provide a more reasonable and scientific reference for the selection of relevant parameters in the process of predicting old water volume in the future.
