采矿崩落区降雨迳流渗入量计算

Calculation of rainfall runoff infiltration for mining caving area

以开阳磷矿区马路坪矿为例,描述其矿山随着采矿深度的增加造成地表开裂变化及其矿坑水的水量变化和溃入矿坑的相关因素的演变过程和规律。并在此基础上探索采矿崩落区降雨迳流渗入量的计算方法。

Taking Maluping mine, Kaiyang Phosphate Ore Zone as an example, change of mine water amount, its evolution process and law of correlated factors to crush into the pit due to ground surface crack with increases in mining depth, are described. On lhis basis calculation method runoff infiltration for mining cave area is introduced.
