摘要
以淮南煤田新集煤矿井田13-1#煤层为研究对象,探讨大型推覆构造对煤层厚度及稳定性的影响。据对98个钻孔资料的统计分析,揭示了该井田推覆体内和原地系统内13-1#煤层厚度变化较大,其变异系数达到34%和30%,超过邻近的未受大型推覆构造影响的张集井田以及淮南其他井田该煤层厚度的变异系数。
Taking the coal seam of No？？13-1 # well in Xinji Coal Mine of Huainan coal field as the study object,the paper explores the impact of large nappe structure on coal seam thickness and its stability？？ The statistics on 98 boreholes data reveals that the thickness of coal seam No？？13-1 # changes greatly in the nappe body and autochthonous system,and the variation coefficients reach 34% and 30%,which surpass that of the nearby ZhangJi mine field not affected by the large nappe,and other mine fields of Huainan.
