Open air mine semicontinuous conveying system single line slope conveying designing method

Abstract

In the invention, transportation from exploitation breaking station down to bottom of surface mine is designed according to normal motor vehicle transportation, and main transportation road includes dual lanes. Character is that road going up from exploitation breaking station is designed according to condition of single line and high slope. Width of platform of transportation line or single vehicle is 14-19m, longitudinal slope as 12-15%. Buffering platforms are setup in middle staggering zone in width 25-30m and length 40-60m of gentle slope in use for staggering vehicles or breakdown maintenance. The invention increases slope angle, reduces quantity of stripping rock, and stripping ratio.

Description

technical field

[0001] The invention belongs to the field of mining, in particular to a design method for single-line steep-slope transportation of an open-pit mine vehicle-belt semi-continuous transportation system. Background technique

[0002] As the mining depth of open-pit mines continues to decrease, the distance of ore and rock transportation continues to increase, and the efficiency of equipment transportation continues to decline, resulting in an increase in the cost of ore. When the mining depth of the open pit mine exceeds 300m, the car-tape semi-continuous transportation has obvious advantages. The foreign production practice shows that: the car-belt semi-continuous transportation process is the development direction of the deep concave open-pit mine transportation. According to the foreign design and actual mine production, the transportation road of the automobile-belt semi-continuous transportation process generally adopts a double-lane design, and the design...
