The optimization analysis of numerical simulation of coal-lane's support in the complex condition

LIU Peng,WANG Chun-bo (School of Civil Engineering,Hebei University of Engineering,Handan 056038,China)  
The process of coal-lane's digestion and support are simulated by the two-dimensional finite-different computer codes(FLAC) on the ground of 2610 working place belonging to Dongpang Mining of Jinniu Energy Corporation of Hebei and the design of support is optimized aimed at anchor rod or anchor cable in the surrounding rock unbroken.The simulation results showed that the plastic zone reduced largely and integrity of surrounding rock increased after applying optimum support parameters to coal lane.The actual project confirms perfectly that it is a feasible method in the support of coal mine and acquires very well effects of technology and economy.
