煤层开采后覆岩导水裂隙带高度的模拟研究

Simulation Study on the Height of Water Flowing Fractured Zone After Coal Seam Mining

摘要: 某矿为安全开采煤炭资源，采用经验公式预计和计算机数值模拟方法，按规划设计开采煤层厚度分别研究了单独开采16^#煤、17^#煤后覆岩导水裂隙带高度，采用经验公式计算为36.1 m和29.7 m；采用计算机模拟方法计算为37.1 m、26.9 m。研究了按规划设计开采煤层厚度将16^#煤、17^#煤全采后覆岩导水裂隙带高度为41.7 m。

Abstract: For the safe mining of coal resource, depending on the designing mining height, a mine applied the two methods of empirical formula and numerical simulation to study the height of water flowing fractured zone of 16^# and 17^# coal seams which are exploited alone. The result shows that these two values are 36.1 m and 29.7 m according to the empirical formula, and 37.1 m and 26.9 m according to computer simulation. Depending on the designing mining height, the height of water flowing fractured zone of 16^# and 17^# coal seams after mining is 41.7 m according to computer simulation.
