摘要
为解决1.0~1.4 m薄煤层高效、智能化开采所面临的问题,经过深入研究,以石圪台煤矿首个1.4 m薄煤层综采工作面22~上303-1工作面为研究对象,利用数值模拟、现场应用以及工程类比等手段,在垂直进刀、煤机长度、回采技术以及信息化方面进行技术攻关,形成一套1.4 m及以下薄煤层成套等高装备关键技术。实践证明:煤机机身长度不到4 m、机头机尾实现垂直进刀工艺、自移机尾超长搭接技术、无人化推进、自动拖缆装置、UWB人员接近安全防护系统、本安型巡检、惯导、三维扫描等多种机器人的应用,保证了薄煤层综采工作面的无人化安全高效回采。薄煤层成套等高综采装备选型及配套合理,不仅可以满足综采工作面正常生产,而且采煤效率可提升20%。该成套装备、工艺及关键技术的研发和应用,为薄煤层低采高工作面的回采提供技术指导和借鉴。
In order to solve the problems faced by the efficient and intelligent mining of 1.0-1.4 m thin coal seam,Shendong,through in-depth research and bold innovation,takes 303-1 working face on 22,the first fully mechanized mining face of 1.4 m thin coal seam in Shigetai Coal Mine as the research object,and uses numerical simulation,field practice and engineering analogy to tackle key technical problems in vertical feed,coal machine length,mining technology and informatization,form a set of key technologies of complete set of contour equipment for thin coal seams of 1.4 m and below.Practice has proved that the length of the coal machine body is less than 4 m,the vertical feed technology of the head and tail,the super long lap technology of the self moving tail,unmanned propulsion,automatic towing device,UWB personnel access safety protection system,intrinsically safe patrol inspection,inertial navigation,three-dimensional scanning and other robot applications ensure the unmanned,safe and efficient mining of the fully mechanized mining face in thin coal seam.The selection and matching of complete set of equal height fully mechanized mining equipment in thin coal seam are reasonable,which can not only meet the normal production of fully mechanized mining face,but also improve the mining efficiency by 20%.The R&D and application of the complete set of equipment,process and key technologies provide technical guidance and reference for the mining of low mining height working face in thin coal seam.
