摘要
该文通过地质资料和巷道支护情况,分析围岩变化规律,认为原有锚杆支护失效严重,确定了施工锚索钢带、木垛和π型钢棚的综合加强支护方式;确定了回采期间工作面和空巷夹角的控制、顶板管理、运输机管理及安全措施,为类似地质条件开采提供了理论参考和工程借鉴.
Through the analysis of the variation laws of surrounding rocks on the basis of the geological condition and tunnel support,this article notes that the original bolt support is seriously ineffective.The comprehensive reinforcement support method composed of anchorage steel strip,wooden chock andπ-type steel shed is established.Then the control of the angle between empty roadways,bolt stope roof management,conveyor control and relevant safety measures are determined,which may provide theoretical and engineering references for similar geological condition mining.
