摘要
以平煤股份有限责任公司一矿戊10-22040工作面为工程背景,对下分层工作面开采的大断面切眼巷道提出了3种支护方案,利用FLAC3D数值软件对各种方案进行了模拟分析,得出了最优方案。现场实践证明,架棚支护方式有效控制住了围岩移近量,保证了综采设备的快速安装。
Based on Wu10-22040 face,three kinds of supporting schemes are proposed for the roadway with the large section cutting hole of lower layer mining in No.1 Coal Mine of Pingdingshan Coliery Co.,Ltd.By using FLAC3D numerical software,various solutions are simulated,and the optimal scheme is obtained.The field practice proves that the frame roof support can effectively control the close volume of host rocks,and ensure guick installation of fully mechanized equipments.
