Rock Bolting Numerical Simulation Research and Application of The Face Breakthough
This paper analyzes the importance of rock bolting in coal mining, and the difficult of using rock bolting in breakthough with the affect of mining, adopt hydraulic fracturing and coal-rock mass strength test methods to test the seam stress and rock strength. Make the numerical simulation of break though bolting solutions in coal mine roadway by using FLAC3D software, simulate the different distributions of pre-stressed in coal-rock with three situations, the same raw distance but different space, the same space but different raw distance, impose different preload on the roof anchor in the rock bolting of mine roadway breakthough. Then determine a reasonable bolting solution of coal mine roadway according to the case of prestressed in coal-rock.
