Introduction to the current situation of main mining equipment in underground mines in China: (1) rock drilling machinery pneumatic rock drills are still used in all mines. The high-efficiency hydraulic rock drill widely used abroad has not been popularized and applied in China. Several hydraulic rock drills have been developed in China, but they are rarely used in production. A few mines have used mining or tunneling drill trucks, but

(1) rock drilling machinery

pneumatic rock drills are still used in all mines. The high-efficiency hydraulic rock drill widely used abroad has not been popularized and applied in China, and several hydraulic rock drills have been developed in China, but rarely used in production. A few mines use mining or tunneling drill trucks, but most of them are imported drill trucks, and few of them are developed and used in China

(2) loading machinery

electric rake is still the main ore drawing equipment in some mines; At present, most of the sensor sub mines have used diesel or electric LHD; Some mines still use the early pneumatic or electric bucket rock loader to load rock, and the electric locomotive to tow the ordinary tramcar for transportation; Some mines use shovels and shovels, vertical claw loaders to load rock, and shuttle trams to transport it

(3) raise boring machinery

raise boring is more common with the conventional bucket method, and the common method with a high degree of product introduction of labor qiangsda high-tech plane scroll spring fatigue tester also accounts for a large proportion, while the drilling method with raise boring machine as the main equipment has developed, but it is not common, and has only been better applied in soft rock mines. All pneumatic rock drills used in underground metal mines in China are made in China, and their manufacturers are Shenyang pneumatic tool factory, Tianshui pneumatic tool factory, Nanjing Engineering Machinery Factory, etc. The manufacturers of a small number of pneumatic or hydraulic drill trucks used are Shenyang pneumatic tool factory, Xuanhua pneumatic machinery factory, Shenyang nonferrous metallurgical machinery General Factory, Nanjing Construction Machinery Factory, etc. At present, most of these drilling trucks are products produced by introducing the technology of foreign secoma company or atlas company. The electric harrows used are all domestic, and the main manufacturers are Jinzhou Mining Machinery Factory and Chongqing mining machinery factory. At present, China's metal mines have about 800 underground scrapers, about 60% of which are imported, about 70% of which are powered by diesel engines, and the bucket capacity ranges from 0.38 to 6.1m 3. Imported machine manufacturers mainly include Wagner mining and construction company of the United States, g.h.h company of Germany, mining equipment company of France, etc. Domestic machine manufacturers mainly include Nanchang general machinery factory, Hengyang Nonferrous Metallurgical Machinery General Factory, Jiaxing metallurgical machinery factory, Jiangxi tractor factory and other units that adopt large flow servo valve system. Domestic products are basically used for the raise boring machine. The main domestic manufacturers are the machinery factory of Changsha Mining Research Institute, and all parts of the raise boring machine are localized
