我矿使用无底柱分段崩落采矿法,工作面矿石装载采用华——1型电动装岩机,通过多年的使用实践,特别是最近几年由于华——1型装岩机使用数量的增多,发现这种装岩机存在一些问题。 一、斗柄的稳定钢绳断绳频繁,几乎每班要进行换修,消耗量较大。全矿每年消耗φ3/8″钢绳3吨左右(近万米,价值6500元左右),即平均每台每年约消耗钢绳100公斤(约300米);稳定钢绳的方杆螺丝、弹簧等消耗也因断绳影响而相应增大。另外斗柄承压导轨磨损较快,平均每台每月需换修一次。
I mine using non-pillar subsidence caving mining method, face loading ore loading using China - 1 electric rock loader, through many years of practice, especially in recent years due to China - 1 rock loader capacity Increase, found that this rock loader there are some problems. First, handle the stability of steel rope broken rope frequently, almost every shift to be carried out, consumption of larger. The whole mine consumes about 3 tons of φ3 / 8 "steel rope every year (nearly 10,000 meters, worth about 6,500 yuan), which consumes an average of about 100 kg of steel rope every year (about 300 meters); square bar screws and springs And other consumption is also due to the impact of broken rope and the corresponding increase.In addition bucket handle pressure rail wear faster, on average, each need to be repaired once a month.
