摘要
研究了构造控制性裂隙与巷道布置不同匹配对回采巷道的稳定性影响规律。分析了裂隙间距)(I、裂隙倾角)(f及其裂隙方位和巷道轴向夹角)(a等因素对巷道围岩收敛变形的影响,提出构造控制性贯通裂隙条件下保证巷道稳定及其维护的裂隙-巷道轴线匹配布置原则。
The influence of multiple kinds of matching of tectonically controlled fissures and the roadway layout on the stability of mining roadway was studied. The effects of fissure spacing (I), the inclination of fissure (φ), the angle of the fissure bearing with the roadway axis (α) on the convergence deformation of the roadway surrounding rocks were analyzed. And the layout principle of matching of fissure and roadway axis for guaranteeing the stability and maintenance of the roadway under the condition of technically controlled connected fissures was proposed.
