| 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36.1m和29.7 m;采用计算机模拟方法计算为37.1 m、26.9m。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。 |
| 关 键 词： | 导水裂隙带高度 计算机模拟 覆岩破坏 “三带”高度 |
Simulation Study on the Height of Water Flowing Fractured Zone After Coal Seam Mining |
|
| 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. |
| Keywords: | the height of water flowing fractured zone computer simulation overburden rock failure " three zones" height |
