摘要
10-202综采工作面开采阶段要揭露陷落柱,为了确保工作面的有效、科学、安全回采,要从工作面水文地质环境出发,引入适宜的技术手段,诸如大倾角工作面支架防倒,超前注浆、支护等措施,通过采用先进的开采技术,科学、有效地通过陷落柱,可以防止透水等安全事件的频繁发生。本文就10-202综采工作面过陷落柱技术分析及应用展开讨论。
10-202 fully mechanized mining face needs to expose the collapse column in the mining stage.In order to ensure the effective,scientific and safe mining of the working face,it is necessary to introduce appropriate technical means from the hydrogeological environment of the working face,such as the measures of support collapse prevention,advanced grouting and support,etc.By adopting advanced mining technology,the collapse column can be passed scientifically and effectively,and the frequent occurrence of safety incidents such as water seepage can be prevented.This paper discusses the technical analysis and application of 10-202 fully mechanized mining face passing through collapse column.
