Laohutai mine in Fushun is one of the mines in which the impact ground pressures have taken place earlier and more frequently.
抚顺老虎台矿是我国发生冲击地压较早、次数较多的矿区之一。
The result showed that the mined-out area can not induce impact ground pressure hazard, but partial caving may occur.
结果表明：该采空区不会发生冲击地压灾害，但可能发生局部冒顶。
This prediction guidance method is divided into two: prediction of impact ground location and search of optimal lateral force.
