SPJ—800胶带机是我国60年代的产品。目前,在一些中小型煤矿采区中,这种设备仍占有相当大的比例。随着煤炭生产的不断发展,多数使用单位反映该设备存在如下问题: 1.运输量小该设备水平铺设时的运输量为350t/h;若用于采区上下山,运输量仅为300t/h右左,只能满足两个炮采工作面同时生产的需要。而目前一般机采工作面的高峰产量可达300～400t/h。尽管一些煤矿在顺槽与上下山之间设置小型缓冲煤仓,但因容量有限,仍影响采煤机生产能力的发挥。2.单机运输距离短该设备水平铺设 SPJ-800 tape machine is China’s 60’s products. At present, in some small and medium-sized coal mining area, this kind of equipment still occupies a considerable proportion. With the continuous development of coal production, the majority of users use the unit to reflect the following problems: 1. Small amount of transportation The equipment is laid horizontally when the volume of transportation is 350t / h; if it is used in the mining area, the volume of transportation is only 300t / h right and left, can only meet the needs of two blast mining face at the same time production. At present, the peak output of general mining face up to 300 ~ 400t / h. Although some mines have small bunker bunkers located between the trough and the up and down hills, their limited production capacity still affects the production capacity of the shearer. 2. Stand-alone transport distance The equipment laid horizontally
