潘集外围4-1煤层顶底板工程地质特征研究

Study on Engineering Geological Characteristics of the Roof and Floor of the 4-1 Coal Seam Around the Outskirts of Panji

通过统计潘集外围4-1煤层顶板30 m至底板20 m范围内岩性分布、岩石力学性质等,本文采用岩石质量指标(RQD)、岩石强度等对岩体质量进行定量评价,为未来矿井建设、巷道布置和工作面设计等提供地质依据。

Based on statistics of the lithology distribution and rock mechanical properties within the range of 30 m from the roof of the coal seam 4-1 at the periphery of Panji to 20 m from the floor,this paper used rock quality indicators(RQD),rock strength,etc.to quantitatively evaluate the quality of the rock mass,in order to provide a geological basis for future mine construction,roadway layout and face design.
