摘要
针对井下回风巷、胶带大巷等煤巷变形压力较大,巷道部分地段受地质构造和煤层赋存状态及矿井整合前小窑采掘破坏等影响,局部多处地段出现不同程度的底鼓、帮鼓、浆体离层、支护材料变形等现象,通过对巷道测压的分析和研究,提出煤巷巷帮侧压变形注浆加固支护应用方案,有效增强了支护强度,控制了巷道变形压力。
Deformation pressures of underground coal roadway such as air return roadway and tape alleys were larger. Some sections of roadway were affected by geological structure, occurrences of coal seam and pre-integrated mining damage caused by small coal, and multiple local locations had different degrees of floor heave, side heave, supporting material deformation phenomena. Through analyzing and researching the side roadway pressure, roadway pressure deformation reinforcement applications were proposed, which effectively enhanced the support strength, and controlled the roadway deformation pressure.
