摘要
以寺河矿南区回风大巷为工程背景,在分析巷道地质条件的基础上,通过理论计算分析了锚杆及锚索的主要支护参数,并确定了锚杆及锚索的型号;结合以往的生产实践经验,确定了巷道联合支护方案。实践表明,巷道支护方案合理,可以满足安全生产要求。
Taking the air return roadway in the south area of Sihe Coal Mine as the engineering background,the main support parameters of the bolt and anchor cable were analyzed through theoretical calculation,and the types of the bolt and anchor cable are determined.Combined with the previous production practice experience,the combined support method of bolt and anchor cable was proposed,and the combined support scheme of roadway was determined.The practice shows that the roadway support scheme is reasonable and can meet the requirements of safety production.
