Technology of Preventing Rock Burst by Lateral Layout Roadway Near Goaf

In order to prevent rock burst hazard of roadway near the goaf in advance, the paper used theoretical analysis to reveal the mechanism of rock burst fail ure and theoretical basis of frequently rock burst for roadway near the goaf, which was according to the model of rock burst failure of roadway under dynamic load and static load. Based on the main components of the dynamic load and static load, two models and necessary criterion were concluded. The lateral layout technology of ro adway near the goaf was proposed to reduce dynamic load and static load. And it was determined that the principle of lateral layout which avoided concentration area 0 f bearing stress to induce static load and increase attenuation coefficient of the propagation medium to weak dynamic load. Finally, the technology was successully pra cticed in Yuejin Mine. Significant and effective effect of rock burst prevention was achieved.
