攀钢矿业公司朱家包包铁矿采用铁路公路联合开拓运输方式 ,矿山铁路移动线都使用木质旁弓杆 ,每年消耗木质旁弓杆 1 0 0 0多根 ,不仅增加采矿成本 ,而且大量砍伐小松树 ,破坏自然环境。自 1 998年 ,朱家包包铁矿开始研制非木质旁弓杆 ,经研究人员 2 a多的努力 ,于 2 0 0 0年 7? Panzhihua Iron and Steel Company Zhuhai package iron ore using railways to jointly develop transport modes, mining railway lines are used to move the side of the bow next to each other, the consumption of more than 1 000 wooden paraxial rods, not only increase the cost of mining, but also a lot of logging Small pine trees, destruction of the natural environment. Since 1988, the Zhuhai-Baotou iron ore mine began to develop non-woody side bow rods. After more than 2 years of research work by researchers,
