目前在我国已逐渐采用电耙运矿石和废石(充填材料)是有特殊有利条件。因为它能力大、机体轻便,使用范围广,所以电耙将要逐渐的在我国得到更广泛的使用。电耙除了在缓倾斜矿体耙矿及充填废石之外,在急倾斜矿床开采里则大多用电耙坑道,用它来耙运近距离矿石,降低运搬工人的体力劳动。近年来由于采矿效率的急剧增加。同时深孔崩矿的逐步发展和巩固,因此,矿石采下的尺寸也在逐步增大,对解决这个繁重的二次破碎工作的研究,现在
At present, electric rake is gradually adopted in our country to transport ore and waste rock (filling material), which has special favorable conditions. Because of its ability, light body, the use of a wide range, so electric rake will gradually be more widely used in our country. In addition to raking ore and filling waste rock in gently inclined ore bodies, electric rakes mostly use electric rake tunnels in the mining of steeply inclined ore beds, and use them to rake up close-range ore to reduce the manual labor of transporting workers. In recent years due to the dramatic increase in mining efficiency. At the same time, the deep-hole collapses ore gradually develops and consolidates. Therefore, the ore mining size is also gradually increasing. Now the research on solving this heavy secondary crushing work is now
