摘要
为了解决陕北黄土沟壑区煤炭开采衍生灾害较难评价的问题,提出概率积分预计参数中下沉系数的确定方法;确定了煤炭开采衍生灾害的评价指标:地表最大下沉值、坡体稳定性和裂缝发育程度;借助概率积分法进行地表移动预计,给出一种陕北黄土沟壑区煤炭开采衍生灾害评价方法。通过实例验证,表明该评价方法可靠,研究成果可为陕北黄土沟壑区煤炭开采衍生灾害防治提供科学依据。
In order to solve the problem that it is difficult to evaluate the derivative disaster of coal mining in loess gully region of northern Shaanxi,the method to determine the subsidence coefficient in the parameter of probability integral prediction was put forward;the evaluation index of coal mining derivative disaster was determined,including maximum surface subsidence,slope stability and fracture development;based on the probabilistic integral method to predict surface movement,an evaluation method of coal mining derived disaster in loess gully region of northern Shaanxi was presented.The results show that the evaluation method is reliable and the research results can provide scientific basis for the prevention and control of coal mining derived disasters in the loess gully region of northern Shaanxi.
