东胜矿区浅埋煤层综采条件下岩移参数规律研究
|
摘要
为了研究东胜矿区地表移动参数与地质采矿条件之间的关系及其特点,基于已获得的东胜矿区内12个工作面地表移动规律研究基础上,利用Matlab与SPSS的回归分析方法,研究了东胜矿区煤层开采引起的地表移动变形角值参数和概率积分法地表移动变形的计算参数与地质采矿条件之间的关系,建立了东胜矿区地表移动参数与相关地质采矿条件的关系式。研究结果表明:边界角、移动角、裂缝角与基岩厚度和采厚的比值相关性较大;下沉系数与采厚和基岩厚度相关性较好;水平移动系数与松散层厚度和基岩厚度相关性较好;主要影响角正切与采厚和基岩厚度相关性较好;而拐点偏移系数与地质采矿条件无显著关系,但存在变化范围为0.04～0.37,对东胜矿区煤层开采地表移动参数可以进行预计。
In order to study the relationships and characteristics between the surface movement parameters and geological mining conditions of Dongsheng Mining Area,based on the study results of the surface movement law of 12 working faces in Dongsheng Mining Area,the regression analysis method of Matlab and SPSS were used to study the relationships between the surface moving deformation angle parameters caused by coal seam mining in Dongsheng Mining Area and the calculation parameters of surface displacement deformation by probability integral method.The relationships between surface movement parameters and related geological mining conditions in Dongsheng Mining Area was thus established.The results show that boundary angle,displacement angle and crack angle are highly correlated with the ratio of bedrock thickness and mining thickness; the subsidence coefficient has a good correlation with coal seam thickness and bedrock thickness; the horizontal movement coefficient is correlated with loose layer thickness and bedrock thickness; the main influence angle tangent is well correlated with the height of the mining and the thickness of the bedrock; and the offset coefficient of the inflection point has no significant relationship with the geological mining conditions,but the variation range is wihtin 0.04 ～ 0.37,which can be used for the prediction of surface movement parameters in Dongsheng Mining Area.
