The development mining machinery equipment is the Chang sha mine research institute constructs the courtyard initial on the establishment discipline, gradually grows strong into one of main body disciplines. 20th century 50, the 60's, mainly are engaged in the development mine small excavation equipment. The 70's started to develop, to apply open-air have opened use dive the hole drilling machine, dive the hole impact, the cutter drilling machine, as well as the electricity drive wheel automobile, front end the type car loader and so on, greatly enhanced our country metallurgy open-air mine perforation and the shipping craft mechanized level.
The underground mining aspect, Big dump accommodated the underground carry-scraper and outside jiang rotate the rock drill development gradually realizes for the our country underground mine rail less has laid the foundation. The shaft, The level grub enter the mechanized production line and the courtyard hang Methods, the courtyard drilling machine research, created the shaft month to enter the ruler 100 meters, the alone even lane month entered the ruler 1,056 meters, the courtyard drilling machine enhances 3~4 compared to the common law tunneling speed to double, created the national record, greatly sped up our country mine construction speed.
80th, the 90's, "thousand 10 thousand-ton large-scale open-air mines complete set of equipment research", has filled our country heavy mining equipment blank, had finished the long-term dependence import history, obtains the State Council to issue an order the praise, and attains country technological special class prizes. The underground mine railless equipment development, enhanced our country underground mine railless mining technology the new level. The underground cutter drilling machine, dives the hole drilling machine series product and the courtyard drilling machine series product development, for our country underground ore strengthening mining and the courtyard security, the quick intensive well has provided the reliable equipment. Above the achievement once caused the Chang sha mine research institute to be in eagerly anticipates the domestic mine mechanization technological development direction the important status.
In the recent ten years, besides further deepen the original mine equipment research, but also undertook "95", "15" in the national science and technology attack project have been big, the medium underground carry-scraper development, the MARK-36 154 ton select ricity drive wheels mineral product dump truck development, in the depth portion excavation technology synthetic study equipment development, imported the equipment the digestion absorption and the spare parts domestic product research, the big room column centralization do not have µ×Öù mine in the new craft research equipment development, the science and technology department courtyard project intelligence hydraulic pressure stone crusher development, the well lane not damage the mechanized tunneling seriation cutting tool the research and so on.
The high-pressured water jet flow technology is on the century 70'semerging one kind of merit many, the use is broad, involves many disciplines the high-tech. My courtyard in the domestic start most early, has started since 1978 to study the high-pressured water jet flow technology, cuts technical and the equipment, the water jet flow clean technology and the equipment, the water jet flow scale removal technology and the equipment, water jet flow aspect and so one excution machines and tools and equipment in the water jet flow makes the massive developments to study and to promote the application work, has yielded the nearly 20 scientific research results, more than 10patents, attain the country technological award third prize 1 item, the province department level science and technology prize second prize 5 items, the third prize 8 items. In 1990 the Shanghai science and technology education motion picture studio produced this scientific research achievement the popular science film "Water Charm" in national public showing, the Central Committee Television, the Hunan television station "reads extensively it in the science and technology", "the economical half hour" and so on the column broad cast that, affected profoundly.
This technology versatility, may use in to clean, to remove dirty stuff, the exhausted level, eliminates the rust, cuts, the drill hole, brokenly, the scale removal, the clear granulated substance, the atomization, the note thick liquid, Shui La, the fire prevention and so on, involves mining, the aerospace, the colored metallurgy, the steel and iron, the electric power, the ships, the petroleum, the chemical industry, the machinery, the building materials, the building, the light industry, the war industry, the agriculture, the medical service and so on the multitudinous department. Since specially this research topic group has expanded the research institute in 1995 to establish in ten years, had the surmounting ¨Clike development in the scientific research achievement industry aspect, has stepped onto the branch labor trade integration development speed way.
