综放工作面过空巷超高水材料充填技术
|
摘要
为保证12305综放工作面过风运联巷时安全回采,在综合对比的基础上,决定采用超高水材料对巷道进行充填。本文详细介绍了超高水材料的特性,包括强度特性、凝结时间和流动性等,结合该联巷的实际条件,超高水充填体采用自流的方式直接进入巷道。通过采用超高水材料充填保证了12305工作面的安全回采,取得了较好的经济和社会效益。
In order to ensure the safe mining of 12305 fully mechanized coal caving face while passing finished mining roadway in Jindi Mine,the super high-water material was chosen to fill the roadway based on the comprehensive comparison.The characteristics of this material,including strength characteristics,setting time and fluidity,were introduced in detail.Combined with the actual conditions of the roadway,the material filling body was directly entered into the roadway by the way of self flow.Through the use of super high water material filling,the safe recovery of 12305 working face was ensured,and achieved significant economic and social benefits.
