摘要
Abstract
This article has introduced ground collapse caused by goaf of adjacent coal mines—Tingnan and Dafosi.After the contrastive analysis,it has put forward that obvious differents of the effective ratio of length to depth,the effective ratio of depth to thickness,overlying strata mechanical properties,different mechanical properties rock layer thickness are the different geological disaster＇s primary cause by two types goaf,and based on the effective ratio depth to thickness,it havs divided the different geological disaster range of distribution and the degree of risk to the village.关键词
