新上海一号煤矿8号、15号煤层顶底板工程地质特性分析

Analysis on engineering geological characteristics of No.8 and No.15 coal seam roof and floor in New Shanghai No.1 Mine

在矿井建设和开采过程中,经常会出现威胁煤矿安全生产的煤层顶底板事故,不仅影响井巷的施工还对煤层的开采造成威胁。因此,对煤层顶底板工程地质特征研究就显得非常必要。现以新上海一号煤矿8号、15号煤层顶底板为研究对象,通过利用煤矿勘探资料和岩石物理力学性质对煤层顶底板岩体质量及其稳定性进行评价与分析,并结合煤矿的构造发育特征对顶底板可能产生的危害进行预测,对煤矿安全生产具有重要意义。

In the process of mine construction and mining,coal seam roof and floor accidents threatening the safe production of coal mine often occurred,which not only affected the construction of roadways but also threatened the mining of coal seams.Therefore,it was very necessary to study the engineering geological characteristics of coal seam roof and floor.Taking the roof and floor of No.8 and No.15 coal seams in New Shanghai No.1 Mine as the research object,the rock mass quality and stability of coal seam roof and floor were evaluated and analyzed by using the coal mine exploration data and rock physical and mechanical properties,and the possible damages of the roof and floor were predicted in combination with the structural development characteristics of the coal mine,which had great significance to the safe production of coal mine.
