| 摘 要： | 针对任楼煤矿开采72煤过程中,巷道在强大的动压作用下,破坏严重的情况,从岩性组成、岩层组合类型和顶板岩体结构三个方面,研究了煤层顶板岩体特征。研究结果表明,72煤顶板岩体岩性以软岩为主,岩层组合以"直接顶+老顶"的组合形式为主,岩体结构以碎裂和块裂结构为主。研究结果为巷道布置、支护形式选择、顶板管理提供了科学依据。

| Abstract: | In allusion to serious destruction of roadway under the strong dynamic pressure during the mining of No.72 coal in the Renlou coalmine, coal roof rock mass characteristics have studied from three aspects of lithology, strata assemblage type and roof rock mass structure. The results have demonstrated that the lithology of No.72 coal roof is mainly soft rocks; strata assemblage is mainly ＂ immediate roof ＋ main roof＂ assemblage; while the rock mass structure is mainly cataclastic structure and blocky fractured structure. The findings can provide roadway layout, support pattern selection and roof control with scientific basis. |
