Granite mining is generally divided into the following steps:
In granite mining, the first mining area shall be selected according to resource conditions and market demand, and the mining boundary, production scale and working system of the mine shall be determined.Mining is carried out on the basis of comprehensive analysis of natural environment, economic and technological conditions.The mining process can be divided into development transportation, stripping and mining.
Develop transport and loading
The task of development and transportation is to open up the transportation path from the mining area to the working steps in the stope and the transportation path to the waste rock field.The commonly used development and transportation modes of granite open-pit mines are:
(1) highway development of automobile transportation, which is flexible and flexible, can give full play to the efficiency of loading equipment, is widely adopted.
(2) trenchless open mast crane lifting, this method does not need to dig the transport channel from the surface to the mining steps, and directly by the mast crane loading transport equipment.This method has a small amount of engineering, low investment, but limited by the capacity and working range of mast crane, poor flexibility.
In addition, there are slope hoist road development trolley transportation, road car and mast crane joint development transportation and other ways.
There are two types of loading equipment for loading raw materials onto the transport equipment: stationary type and mobile type.Mast crane is fixed, this kind of equipment lifting height, lifting weight, both loading and transport functions;Crawler crane and wheel crane are mobile loading equipment, this kind of equipment is flexible, but the lifting height, lifting weight is small, not suitable for large size bulk material loading.Mine waste rock transport commonly used manual carts, front loading, bulldozers, cranes, automobiles and other equipment.
