摘 要:为保证悬臂式掘进机采矿作业效率及矿山生产系统的匹配适应性,依据设备配套选型原则,提出了掘进机、通风除尘和供电系统设备配套选型方法。根据矿山工程、设计进行掘进机设备初选,建立了岩体单轴抗压强度、抗剪强度与破岩所需截齿截割力的关系模型,对比各初选设备所提供截齿截割力与破岩所需截割力,提出了富余系数概念,在保证破岩能力的基础上,选择富余系数合理的掘进机机型;计算通风除尘、供配电系统设备主要参数,根据结果进行主要配套设备选型。选取某矿区做选型方法验证,结果表明:选取满足破岩要求且富余系数为209%的EBZ160型悬臂式掘进机进行工业试验,单日生产效率最大可提高3.56倍,所选通风系统与配电系统设备满足生产需求,证明该选型方法在金属矿山机械开采中具有良好的应用效果。In order to ensure the mining efficiency of cantilever roadheader and the matching adaptability of the whole production system, according to the selection principle, the supporting equipment selection method of roadheader, ventilation and dust removal and power supply system equipment is proposed. According to the general situation of mine engineering and design, the primary selection of roadheader equipment was carried out. The relationship model between the uniaxial compressive strength and shear strength of rock mass and the cutting force required for rock breaking was established. The cutting force provided by the primary selection equipment and the cutting force required for rock breaking were compared. The concept of surplus coefficient was proposed. On the basis of ensuring the rock breaking capacity, the roadheader with reasonable surplus coefficient was selected. The main parameters of ventilation and dust removal, power supply and distribution system equipment were calculated and the main supporting equipment was selected according to the results. A mining area was selected to verify the selection method. The results show that the EBZ160 cantilever roadheader which meets the requirements of rock breaking and the surplus coefficient is 209% can be selected for industrial test. The daily production efficiency can be improved by 3.56 times. The selected ventilation system and distribution system equipment meet the production requirements, which proves that the selection method has a good application effect in machinery mining of metal mines.
