Chifeng is the birthplace of tunnel drilling rig, led by Guilin Research Institute in the 1970s, Chifeng non-ferrous metal mine drilling rig repair factory is the only designated production unit of national tunnel drilling rig, after 30 or 40 years of industrialization after reform and opening up, China's economic level and industrial level have been rapidly developing. Domestic non-coal mine full hydraulic tunnel drill manufacturing industry has also made no small achievements.

In fact, since the establishment of Xi 'an Research Institute of the General Institute of Coal Science and Research in May 1956, there have been no small achievements in the fields of coal geology and exploration, coal mine hydrogeology and engineering geology, coal field geophysical exploration, coal mine underground drilling equipment and technology, and later Xi 'an Institute has become the largest and most complete specifications and models of coal mine tunnel full hydraulic drill research and development and production base. On March 18, 1993, the Ministry of Geology and Mineral Resources of the People's Republic of China issued the "Technical Conditions of tunnel drilling Rig" in the "Geological and Mineral Industry Standard of the People's Republic of China". In 1993, Xi 'an Institute ranked first in the geological survey and exploration industry in the investigation and evaluation of the State Science and Technology Commission, and entered a period of vitality after restructuring in 1999. According to the needs of China's actual national conditions, the development of coal mine hydraulic tunnel drilling rig mushroomed rapidly, and soon there was a perfect system and standards, and the development of non-coal mine, metal mine drilling industry is lagging behind, so far in use of China's Ministry of Metallurgical Industry Geological Bureau in 1982 part of the industry standards.
After understanding the simple history of the development of China's tunnel drilling rig, the following briefly introduces the difference between coal mine tunnel drilling rig and non-coal mine tunnel drilling rig:
1, coal mine underground need explosion-proof, so the design of coal mine tunnel drill needs to consider from the structure to avoid dust accumulation, consider explosion-proof, although we have seen the coal mine tunnel drill feels from the appearance to the principle and Chifeng production of non-coal mine tunnel drill no difference, but need to use qualified explosion-proof motor, and explosion-proof distribution cabinet, the drill needs to have MAC that is coal safety certification. Chifeng non-coal mine drilling rig does not need explosion-proof design, belongs to the general industry field, does not need coal safety (MAC) certification and mine safety (KA) certification, also does not belong to the special industry, does not need safety production license, implementation of the Ministry of Metallurgical Industry Geological Bureau standards.
2. The speed and system pressure of coal mine drilling rig are more suitable for the rock formation characteristics of coal mine, while Chifeng full hydraulic tunnel drilling rig is more suitable for geological exploration of non-coal mine and metal mine, and each has its own application.
3, the constant power output variable oil pump and quantitative motor used in coal mine tunnel drilling rig will automatically change the output speed and torque according to the size of the load, which is not suitable for non-coal mine geological exploration. Because the rock structure of metal mines and non-coal mines is more complex, the speed and torque need to be adjusted according to different geological characteristics, so Chifeng's full hydraulic tunnel drill adopts quantitative oil pump and variable motor, each has its own professional field.
4. The model name of coal mine tunnel drilling rig is usually named after the output torque, beginning with "ZDY"; Non-coal mine, metal mine full hydraulic tunnel drill named after the drilling depth, beginning with "KY". There are also some named after other letters belong to the implementation of their own internal standards, their own system.
After a brief introduction, is it possible to have a basic understanding of their respective application fields in the face of different forms of drilling rig products with the name of "full hydraulic tunnel rig"?
