摘要
无煤柱开采沿空留巷是我国采煤技术发展方向。近几年来,为了探求合理的巷旁支护方法,几个矿区试验了高水速凝泵送充填新技术。本文主要介绍了巷旁充填技术的进展及实践经验。
No coal pillar mining with reuesed roadway is a coal mining technical development tendency in China coal. Over the pass 40 years, personnel from research institutions, colleges and schools, and coal mines have done a lot of research and test work on support of reused roadway. Certain results have been obtained from the research and test work which have played a certain role in coal production. The previous supporting technology did not well developed and the main causes are as fallowings, such as unsufficient support resistances, relationship between yield and roof-floor convergence, heavy haulage, high labour and high cost. In order to to chnage the above stated, and search a new technology, some trial on high-water content, quick setting pumping material for filling reused roadway have been made in some coal mines. This paper is to introduce the principle and practice of the new technology.
