[Types and Elements of Stone Mines] [Deposit development and development transportation method] [Mining process of stone deposit] [Classification of Mining Methods for Stone Mines] [Types and Elements of Stone Mines] I. Types of Stone Mines The types of stone mines include open-pit mining and underground mining. Open-pit mining is divided into hillside open-pit mining, sunken open-pit mining and well mining. Underground mining is divided into cave mining and shaft mining. 1. Open-pit mining: A stone mine in which the overburden and weathered layer on the surface of the stone ore body need to be stripped before mining. An open trench is dug from the ground and a working face is created to extract the block from the working face. According to the topographic conditions of deposit burial, the mining above the lowest level of stope surface is called hillside open-pit mining; the mining below the lowest level of stope surface is called depression open-pit mining. Open-pit mining on hillside: Basically according to the principle of top-down mining sequence.

Sunken open-pit mine Well-type mining: In fact, it is a special case of open pit mining. With the deepening of stone mining operations, many stone mines have gradually evolved from hillside open-pit type to depression open-pit type, and eventually to well mining. The depth of many well-type mines in foreign countries exceeds 50 meters, or even reaches 80 meters or more. Portuguese pink marble CARRARA, Italy 2. Underground mining: Stone mines that need to be excavated from the surface to reach the ore body can be divided into roadway (cave) mining and chamber (roadway) mining. Cave type: Open-pit mines with steep mountain shape, large amount of stripping and extremely dangerous mining operations, such as some marble mines in Baoxing County, Sichuan Province; sunken open-pit mines with inclined ore bodies, with the increase of mining depth, need to strip a large thickness of overburden, such as white marble mines in Fangshan, Beijing; With the increase of mining depth, the mining of some well-type marble mines will not be able to continue. Advantages and disadvantages: High efficiency (1.5 ~ 2.5 /H), flexibility, large cutting depth (up to 10 m), large cutting area, smooth cutting surface, not affected by season and climate. High noise (100 ~ 120 db), high dust, high fuel consumption, high cost (200 ~ 250 yuan/) and high labor intensity, so it must be combined with other mining methods. Flame cutting machine combined with hand-held rock drill,dth drill bits, drilling row holes combined with splitting mining method (referred to as burning rock drilling mining method) is the traditional, longest and most widely used granite mining method.
