上坪矿区巷道压力控制及支护现状探讨

Discussion on the status quo of roadway pressure control and support in Shangping mining area

当前,上坪矿区安全支护工作耗费的资金成本较高,多采用混凝土材料,使用效果有限。在矿区的特殊环境中,需要加大压力控制强度,提高支护质量状况。材料中的应力状态、内部结构等因素都会影响巷道矿体压力状况,需要掌握巷道矿压控制原理,了解巷道压力控制及支护工作的有效形式。本文主要阐述了巷道压力控制及支护现状及有效革新措施。

At present,the capital cost of shangping mining area safety support work is high,the use of pouring concrete materials,the use of limited effect.In the special environment of mining area,it is necessary to increase pressure control intensity and improve support quality.Rock stress state,internal structure and other factors will affect the pressure of roadway rock mass,so it is necessary to master the control principle of roadway pressure and understand the effective form of roadway pressure control and support work.The present situation of roadway pressure control and support and effective innovative measures are described in this paper.
