摘要
朱庄煤矿巷道主要支护形式有砌碹、架棚、锚喷等。由于该矿是一个已开采了 4 0多年的老矿井且进入到深水平开采 ,地应力增大 ,地质条件复杂 ,巷道修复工作量大且支护效果不甚理想。锚注支护是一种主动支护 ,能防止围岩风化 ,使围岩形成一个整体 ,提高支护结构的完整性 ,扩大支护结构的适应性。锚注支护施工简单 ,操作性强。朱庄矿引进锚注技术 。
The laneway main shoring forms in Zhuzhuang Coal Mine are brick laying, shelving and anchor hold etc.As this mine has been mined for more than forty years and in deep level, terra stress fills out geological condition complex. Bolting spouting is an initiative shoring.It can prevent wall rock from airslaking,make wall rock grow one integer, improve the integrality of shoring configuration and extend the adaptability of shoring configuration. The construction of bolting spouting is simple and can be handled expediently.Fetching bolting spouting technology has made good result.
