摘要
针对测区内村庄外围房屋多处出现的裂缝,查明这些房屋下是否有采空区存在,裂缝是否由采空区造成,应用瞬变电磁勘探方法探测资料,并结合开采区的地质和挖掘情况,推断出采空区影响范围,认为村庄外围房屋多数出现的裂缝主要是由采空区造成的。
In view of the existence of quite a few house cracks in villages and periphery of the surveyed area, the authors tried to find out whether there exists a goal and whether the cracks are caused by the goal Data obtained by transient electromagnetic method were used in combination with geological and digging conditions of the mining district to infer the influence range of the goal.. It is held that the cracks in houses in villages and periphery are caused mainly by the goal.
