【摘要】：针对晋陕蒙大型煤炭基地6~9m坚硬厚煤层赋存条件,研究了6~8m超大采高一次采全厚开采关键技术与装备,分析确定了液压支架对围岩控制的六个可控性因素,其中合理的支架初撑力与工作阻力应同时满足支架对顶板与煤壁的有效控制。通过研发Φ500~600mm大缸径抗冲击立柱、控制阀组及供液系统,保障了支架对顶板的支护能力及移架速度。优化设计了超大采高液压支架三级协动护帮装置,开发了Q890~Q1150液压支架用高强度易焊接结构钢,通过轻量化设计实现支架减重15%。研究了超大采高工作面端头大梯度直接过渡配套方式,有效提高了煤炭资源回采率。研究了基于工业以太网的环境及装备智能感知系统,实现了工作面设备间的智能联动与一键启停控制。通过对6~8m超大采高综采成套装备及技术研究与实践,提出了超大采高综采技术装备的适应条件及实施的技术经济性。
[Abstract]:In view of the occurrence condition of 6m hard thick coal seam in large coal base of Shanxi, Shaanxi and Inner Mongolia, the key technology and equipment of 6Gui 8m super-high mining full thickness mining are studied, and six controllable factors for controlling surrounding rock by hydraulic support are analyzed and determined.The reasonable initial support force and working resistance should meet the effective control of roof and coal wall.Through the research and development of 桅 500~600mm large diameter anti-impact column, control valve group and liquid supply system, the support ability and the moving speed of the support to the roof are guaranteed.This paper optimizes the design of the three-stage coaction support for the super-high hydraulic support, develops the high-strength and easy-to-weld structural steel for the Q890~Q1150 hydraulic support, and realizes the weight loss of the support by light weight design.This paper studies the matching way of direct transition of large grads at the end of super high mining face, which effectively improves the recovery rate of coal resources.The intelligent sensing system of environment and equipment based on industrial Ethernet is studied, and the intelligent linkage and one-click starting and stopping control are realized.Based on the research and practice of the complete set of equipment and technology for fully mechanized mining of 6m 8m oversized mining height, this paper puts forward the suitable conditions and technical economy of the technology equipment for super-high fully mechanized mining.
