宁东煤田鸳鸯湖矿区红柳煤矿顶板砂岩的力学特性分析

Analysis of Mechanical Characteristics of Ningdong coalfield Yuanyang Lake Area Hongliu Mine Roof Sandstone

在地下工程中，岩石单轴抗压强度是地下空间开挖和支护的依据。论文以红柳煤矿顶板为研究对象，基于岩石或混凝土等脆性材料力学测试设备，对天然含水率下砂岩的强度进行了研究，为矿井采场管理或巷道支护提供依据。

The underground engineering, the rock uniaxial compressive strength is the basis of underground space excavation and supporting. Papers to Philippine roof in coal mine as the research object, based on the brittle material such as rock or concrete mechanical test equipment, the strength of the sandstone are studied under the natural moisture content, provide the basis for the mine stope management or roadway support.
