在分析国内外综采加长工作面技术发展现状的基础上,从理论和实践2方面就综采工作面加长后工作面矿压规律的变化和工作面配套设备参数的选择等进行了系统研究,结合神东矿区应用情况,对加长工怍面技术应用效果进行了分析,提出该技术的应用前景和发展方向。 Based on the analysis of the status quo of technology development of fully mechanized longwall mining face both at home and abroad, this paper systematically studies the changes of rock pressure regularity and the selection of equipment parameters of working face after the extension of fully mechanized mining face from theory and practice. According to the application in Shendong Mining Area, the application effect of the lengthening caving technology was analyzed, and the application prospect and development direction of the technology were put forward.
