4、ract: The research object is a coal mining goaf in Urumqi Eight Bay Area. Based on the situation andprediction assessment of collapse risk, this paper carries out the comprehensive regional assessment withthe aim to provide ascientific basis for construction land planning and geological hazard contr

Field geological surveys, geophysical exploration and drilling indicate that the hazard risk is modernullate; the forecast evaluation by the maximum height of water flowing the fractured zone and the analyticalmethod show that collapse may continue; and thecomprehensive regionala
