Abstract
In the construction process of-940m main drainage pump chamber in Anju mine, under the guidance of" yield-resistance " supporting theory, optimized the tunneling construction method, one support using cable anchor supporting (initial shotcrete process) ,the two support using reinforced concrete arch support , coupled with the "inverted arch" combined supporting mode, at the same time carrying out mine pressure monitoring. Monitoring shows that the supporting effect is good, in order to solve the large section chamber with kilometer buried depth large deformation, poor stability and hard to maintain of surrounding rock provides a comprehensive construction technology.关键词
