摘要
为了给鹤煤十矿12采区运输机上山巷道支护设计提供科学准确的岩石物理力学性质参数和巷道开挖后围岩破坏范围,通过现场取样,在实验室进行了岩石的物理力学性质测试研究,在上山巷道进行了围岩松动圈现场测试,对测试结果进行了分析研究,确定了围岩松动圈破坏范围,为确定合理的支护形式提供了定量依据。
In order to provide scientific and accurate parameters of physical and mechanical properties of rocks and the damage range of roadway surrounding rock to the supporting design of uphill roadway in Mining District 12 of the No. 10 Hebi Coal Mine,experiments on the physical and mechanical properties of rocks is conducted based on the filed sampling of surrounding rocks. Besides that,the surrounding rocks loose circle is tested on the spot at the same time,the test results are analyzed so as to obtain destruction scopes of rocks loose circle is obtained. The research results in this paper can provide quantitative foundation for selecting the reasonable support forms.
