极近距离煤层开采巷道支护技术研究

Supporting Technology Research of Roadway in Ultra-Close Multiple-seams Mining

针对极近距离煤层巷道顶板破碎,支护困难的情况,以某矿实际条件为背景,确定下煤层巷道合理布置方式,依据层间距大小对巷道顶板进行分类,并对不同类型顶板给出合理支护参数,采用新的支护方案,保证了支护质量,降低了支护成本,为工作面安全生产奠定了基础。

It is difficult to support the roof of ultra-close multiple-seams roadway roof, take actual conditions of a mine as the background, to determine the reasonable layout of coal seam roadway, the roadway roof is classified according to layer spacing, and the reasonable support parameters are given for different types of roof, adopt the new support scheme, ensuring the quality of the supporting and reduces the cost of supporting, laid the foundation for safety mining.
