摘要
矿山地面塌陷,因盖层性质不同,形成形态各异的场陷体。从工程地质上可分成4种塌陷类型,并有一定分布规律,在盖层薄弱带、构造发育带、地下水动力改变带等地,矿山疏放水时易引发塌陷。编制场陷分区预测图,加强监测,是有效的防护措施。
Mine ground collapses, basing on different caprock properties, May form all kinds of different pat-terns. From engineering geology view, they can classify into four kinds of collapes, and have definite distrhutional ragularities. When mine dredge and drain water. It is easy to lead to mine ground collapses in the zones of caprock weak, structure and changing of underwater dynamic. It is effective preventional methods to work out forcasting patternsoof collapse zonalations and strengthen observation.
