| 摘 要： | 根据主采煤层顶底板岩体岩性类型及结构面发育程度对其稳定性进行了评价：72煤层顶板以中等稳定一不稳定类型为主，82煤层顶板以中等稳定类型为主，10煤层顶板以中等稳定一稳定类型为主。在大量统计见煤点硬质岩百分含量（k值）的基础上，结合顶板岩石的单轴抗压强度，对各主采煤层顶底板工程地质类型进行了划分：72煤层以一、二类顶板为主，82、10煤层均以五类顶板为主。综合评价该矿工程地质条件为中等即Ⅲ类二型。根据研究成果，指出该矿在采掘过程中可能出现的工程地质问题，并依此提出了治理建议。

| Abstract: | Based on main mineable coal seam roof and floor lithologieal type and structural plane developing extent appraised their stability： No.72 coal roof is mainly medium stable-unstable; No.82 roof mainly medium stable; No.10 coal roof mainly medium stablestable. Based on large amount coal point hard rock percentage （k value） statistics, combined with roof rock uniaxial compressive strength divided engineering geological type of each main mineable roof and floor： No.72 coal roof belongs mainly to first and second classes; Nos.82 and 10 coal roofs mainly to fifth class. After comprehensive appraisal considered that the coalmine＇s engineering geological condition belongs to moderate that is to say category Ⅲ, type 2. Based on studied results, pointed out that possible engineering geological problems may occur during winning and opening, hereby governing suggestions put forward. |
