Study on Control Technology of Roof and Equipments Withdrawal Roadway in Fully Mechanized Caving Face at the End of Mining

针对综放工作面单通道设备撤出巷支护问题,采用理论分析、数值模拟和现场实测及结合以往工作实践经验,对伊泰京粤酸刺沟矿业有限责任公司6上115综放工作面设备撤出巷支护相关事项进行了研究总结,结果表明:合理的支护方式,可以对末采期间巷道破坏进行有效控制,6上115综放工作面的顺利贯通,验证了支护设计的可行性和适用性。

Aiming at the support problem of single-channel equipment withdrawal roadway in fully mechanized top-coal caving face,by using theoretical analysis,numerical simulation,field measurement and combined with previous work experience,This paper studies and summarizes the matters related to the withdrawal of equipment from roadway support in NO.115 fully mechanized top coal caving face on the 6 th floor of Yitai Jingyue acid Cigou Mining Co.,Ltd.,the results show that the reasonable support method can effectively control the roadway damage during the last mining period,and the smooth penetration of the 6 th and 115 th fully mechanized caving face verifies the feasibility and applicability of the support design.
