摘要
针对庞庄矿-370m东大巷七煤煤柱孤岛工作面压力大,回采困难等问题,在回采过程中采取了相应的技术措施。工程实践表明,通过改善回采工艺、加强顶板支护等,可以安全高效的进行孤岛工作面回采。总结该面回采过程中遇到的问题和采取的技术措施,可为相似工作面回采提供一定的参考价值。
Because of the problems that heavy pressure from the seventh coal Pillar Island faces of the-370m east roadway,and the stopping difficulties at Pang Zhuang Coalmine,Engineering practices demonstrated that island face mining was safely and effectively through improving the recovery process,strengthening the roof support.According to the problems encountered in the surface mining process and the technical measures involved,references are expected to be provided for similar mining faces.
