Abstract: 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.

Key words: Surrounding rocksof roadway, Mechanical properties, Loose circle, Test, Support
