济宁城市规划区开采沉陷概率积分法参数综合研究

Comprehensive study of parameters of probability integral method of mining subsidence in urban planning areas of Jining City

  • 摘要: 济宁城市规划区与区内20多个煤矿采区有重叠区域,为掌握济宁城市规划区的开采沉陷规律,为济宁城市规划提供依据 ,在收集整理城市规划区内岱庄矿的观测站资料和13个煤矿的20条观测线资料基础上,综合分析了各矿井概率积分法参数与采深、采高、表土层厚度及充分采动程度的相关性。研究结果表明:研究区域的下沉系数与采动程度、开采深度具有强相关性,即下沉系数随采动程度增大呈现出增大趋势,而随采深增大呈现出减小趋势,且各因子在下沉系数影响程度上表现为表土层厚度>开采深度>开采高度;水平移动系数与表土层厚度、采深、采高和采动程度无明显强相关性。经统计处理得:与表土层厚度在局部上存在二次函数关系;主要影响角正切与表土层厚度在局部上存在线性相关性,并受到开采深度的约束,随采深增大呈现增大趋势,且在局部上与采高存在“波浪”式函数关系;开采影响传播角在本区域比较稳定,处于86.4°~90.0°。

     

    Abstract: There are overlapping areas between Jining designated urban planning area and more than twenty operating production coal mine areas,which plays an important role in mastering the mining subsidence law of the Jining urban planning area and providing a reference for Jining urban planning. The observation station of t he Daizhuang mine in the urban planning area has been collected and sorted,and based on the comprehensive analysis data and the results analysis data of 20 observ ation lines of 13 coal mines,the correlation between the parameters of the probability integration method of each mine and the mining depth,mining height,surface soil t hickness and full mining degree was comprehensively analyzed. The research results show that the subsidence coefficients of the study area has a strong correlation W ith the degree of mining depth and mining degree,that is,the subsidence coefficient shows an increasing trend with the increase of mining depth,and shows a decreasin g trend with the increase of mining depth. In addition,the influence degree of the various factors on the subsidence coefficient is expressed as follows: the thickness of t he surface soil layer>mining depth >mining height. The horizontal movement coefficient does not have distinct relationship with the thickness of the surface soil layer,mi ning depth,mining height and mining degree. But after statistical processing,it is found that there is a local quadratic function relationship with the thickness of the surfa ce soil layer. The main influence is that the angular tangent and the thickness of the surface soil layer have a local linear correlation and are restricted by the mining de pth,showing an increasing trend with the increase of mining depth,and there is a"wave "type functional relationship with the mining height locally.
