根据现场实际陷落和模拟实验资料知道,在倾斜矿体的矿山,尽管岩层构造面错综复杂,但只要在上(下)盘没有斜交矿体倾向或在矿体中没有沿倾向的大构造面,则采空区上部和两侧的破坏岩层还是大致沿着弧面下滑的。弧线(弧面与矿体横剖面的交线)靠地表那段近乎于竖直,这就是在矿山地表常见到的垂直张裂缝,弧线的下段因破坏面受重力作用而压紧,所以就是通常所观(予)测到的裂纹,而不是裂缝。裂缝与裂纹组成一个个弧面,把倾 According to the actual collapse of the site and simulation data, it is known that in ore-bearing mines, despite the intricacies of the structural planes of the rock formations, as long as there is no inclination to the ore body in the upper (lower) plate or no large structural facies in the ore body, The damaged rock strata in the upper part and the two sides of the goaf glide along the arc surface. The arc (the intersection of the arc and the cross section of the ore body) is nearly vertical to the surface of the earth, which is a vertical crack commonly found on the surface of the mine. The lower section of the arc is compressed by gravity due to the failure surface Is usually observed (pre) measured cracks, rather than cracks. Cracks and cracks form a arc, the dumping
