摘要
某矿21采区中部泵房是该采区疏排水的重要硐室,硐室宽度达到6 m以上,属于典型大跨度硐室,断面使用要求较高。以该矿21采区中部泵房为研究对象,采用调查分析、数值模拟、现场试验等方法,重点研究动压影响下底板大跨度硐室支护技术,深入分析动压影响下巷道围岩活动规律,提出了动压影响下大跨度硐室支护技术。
The central pumping station in 21 mining area is an important dewater chamber of the mining area, chamber widths more than 6 m are typical large span and high sectional requirements underground chamber. Taking 21 mining area central pumping stations as the study object, survey analysis, numerical simulation, field trials and field measurement method are used to focus on the dynamic pressure induced floor large span the chamber support technology, and deeply analyze the dynamic pressure patterns, and put forward support technology of floor large - span chamber effected by dynamic pressure.
