Deep Mining Optimization of Rock Burst Mines

Abstract:

To prevent threaten of impact disaster, high-pressure water is injected into coal face, which is most widely used in impact-type mine. In such cases, by analyzing the rock burst tendency of a particular type of deep mining pit and occurrence of the mining process, rock samples drilled from the coal mine were taken for the conventional mechanical properties test and rock burst tendency test respectively under dry and wet state. Cuttings volume indicator affected by injection has been optimized to improve the prediction sensitivity. "One shift anti-impact, two-shift production "patterns labor organization model, adjusted development system layout and cut drilling index optimizations, as well as the allocation of high-pressure water injection drilling means, greatly improving the water injection effect, which probably provide a reference for similar mines to safe and efficiently mining.
