极近距煤层采煤工艺及可靠性分析

Coal Mining Technology and Reliability Analysis of Close Seam

在分析我国煤层特点和极近距煤层判定标准的基础上,针对极近距煤层的开采提出了相应的采煤工艺。并以某煤矿8243和8245工作面为研究对象,其中以8243工作面为例分析影响工作面可靠性的主要因素,以8245工作面为例分析采用改进采煤工艺后工作面的可靠性提升效果,并为提升8245工作面可靠性提供依据。

Based on the analysis of the characteristics of coal seams in China and the criteria for determining the extremely close coal seam,the corresponding mining technology is proposed for the mining of the extremely close coal seam.Taking 8243 and 8245 working faces of a coal mine as the research object,taking 8243 working face as an example,the main factors affecting the reliability of the working face are analyzed.Taking 8245 working face as an example,this paper analyzes the effect of improving the reliability of working face after adopting the improved mining technology,and provides the basis for improving the reliability of 8245 working face.
