摘要
2202巷回采期间巷道局部顶板、帮部矿压显现明显,变形损坏严重;拟定对该巷道进行补强支护,以缓解巷道局部压力显现,实现工作面安全回采。新补强支护设计通过增加巷道支护强度[1],确保巷道断面尺寸能够满足通风、行人、运输设备等要求;可为其他类似条件的矿井巷道进行补强支护提供经验借鉴。
Aiming at the obvious strata behavior and severe deformation failure in the local roof and sides of 2202 roadway in mining period,the author proposes the reinforcement support design by improving the support strength with section size suitable for ventilation,walkway and transport equipment to relieve the local strata behavior and realize the safe mining,providing a reference for reinforcement support of other mine roadway under similar conditions.
