摘要
针对鄂尔多斯市东胜煤田煤矿开采沉陷引起的地表变形、破坏等问题,基于采动地表移动规律,结合东胜煤田典型煤矿岩移观测台账,采用非线性函数拟合法对采动引发的地表变形规律进行拟合;应用概率积分法进行对比验证,分析得出东胜煤田地表最大下沉速度与采矿条件之间的关系;应用极差和方差进行分析得出各影响因素中最大显著因素。以上研究成果以期为矿井工作面优化设计、采动损害程度评价预测以及采煤沉陷区的生态修复等提供基础参考和科学依据。
Aiming at the problems of surface deformation and failure caused by mining subsidence in Dongsheng coalfield in Ordos,and based on the law of surface movement caused by mining and the observation account of rock movement in typical coal mines in Dongsheng coalfield,nonlinear function fitting method is used to fit the law of surface deformation caused by mining.The probability integral method is used for comparison and verification,the relationship Buertai ween the maximum surface subsidence speed and mining conditions in Dongsheng coalfield is analyzed and put forward,and the most significant factor among the influencing factors is obtained by range and variance analysis.The research results are expected to provide the basic reference and scientific basis for the optimization design of working face,evaluation and prediction of the mining damage degree,and ecological remediation of coal mining subsidence areas.
