【摘要】 本文以乌鲁木齐八道湾地区某煤矿采空区为研究对象,通过野外地质调查、物探、钻探等手段对该煤矿采空区塌陷地质灾害进行现状评估,评估结果为危害程度中等、危险性中等;采用最大导水裂隙带高度法和解析法进行预测评估,评估结果为很有可能继续塌陷;在现状评估和预测评估的基础上,进行了综合性分区评估,将研究区划分为采空塌陷危险性大区、中等区和小区。该研究结果可为研究区建设用地规划和地质灾害防治提供科学依据。更多还原

【Abstract】 The research object is a coal mining goaf in Urumqi Eight Bay Area.Based on the situation and prediction assessment of collapse risk,this paper carries out the comprehensive regional assessment with the aim to provide a scientific basis for construction land planning and geological hazard control in the study area.Field geological surveys,geophysical exploration and drilling indicate that the hazard risk is moderate;the forecast evaluation by the maximum height of water flowing the fractured zone and the analytical method show that collapse may continue;and the comprehensive regional assessment divides the study area into large-,medium-and small-sized sections in the risk of mining subsidence.更多还原
