摘要
针对巷道架棚支护掘进速度慢、支护费用较高等问题,山西赵庄煤矿在分析回采巷道地质条件及开采技术的基础上,通过理论计算确定了锚杆、锚索基本参数,并对回采巷道进行了锚网索支护设计。通过现场观测,验证了其支护参数的合理性,达到了降低支护成本、改善支护状况、保证安全生产的目的。
Aiming at the problems of low drivage speed and high supporting cost in shed supporting of roadway,parameters of roadway supporting,such as bolt and cable anchor,were determined through theoretical calculation based on the analysis on geological conditions of mining roadway and mining technology of Zhaozhuang Coal Mine in Shanxi Province.Field observation proves the rationality of the supporting parameter. The application of this technology reduced supporting cost,improved supporting situation and ensured safety production.
