I. Overview of Jinneng Group
Is a coal, thermal power, clean power generation as the main business, set manufacturing, chemical industry, modern services as a whole, has developed into the country's second largest coal enterprise, Shanxi's largest power generation enterprise and the country's largest basic fertilizer production enterprise.
On September 30, 2020, with the approval of the provincial party committee and the provincial government, the assets related to Shanxi Coking Coal, Lu 'an Chemical, Huayang New Material Coal, Electric Power and Coal Machinery Equipment Manufacturing Industry were simultaneously integrated, and the shares of five coal enterprises, Taiyuan Coal Gasification Company and Huazheng Industrial Company, held by the provincial state-owned operating company were received.
Second, scientific and technological innovation achievements
1, with the development of mine intelligent construction, the output monitoring system has been upgraded successfully, and the analog signal has been upgraded to digital signal, which has stronger anti-interference ability. The new system also has more humanized operation interface and more powerful data analysis function, which realizes all-weather monitoring and whole process coverage of safety production and provides strong support for safety production organization and decision-making.
2. Create an intelligent heading face, and introduce EBZ-200M anchor excavator which integrates the functions of coal cutting, support and electronic fence. Starting with "one-stop", the work is safe, time-saving and labor-saving, and the cutting ability is obviously improved. Each shift can complete the prescribed two regular cycles and become the "main force" of intelligent heading equipment.
3. Through continuous exploration and improvement, the processing speed of the head frame and tail frame of the scraper is improved, and the inner hole milling and boring cutter head is made by ourselves. In the range of boring, the diameter of the self-made boring tool has increased from 550mm to 600 mm This innovation makes the self-made boring tool be regarded as a "permanent boring tool" in a certain sense, with a wide range of applicable blades and strong substitutability.
4. The upgrade of full-face spraying dust suppression equipment can implement measures such as "lowering, removing and reducing" for coal dust in coal yard with full coverage and no dead angle, which integrates dust suppression and cooling functions. As an efficient and energy-saving full-face spray dust suppression device, it can realize intelligent start-stop, time-sharing and subsection control and efficient dust suppression.
5. Made a simple hydraulic press. The control device is a set of hydraulic control valves. By changing the on-off and flow direction of high pressure water, the expansion and contraction of hydraulic jack can be controlled. After using a simple press, bearings, gears, balance wheels and other parts can be easily removed by moving the flap valve under the strong hydraulic pressure.
abstract
Jinneng Group firmly guarantees energy security, and accelerates the construction of a leading modern comprehensive energy enterprise group by accelerating the pace of reform and transformation, enhancing its core functions.
