Tai’feng Group the Wang Village Coal Mine in 2009 took the lead in the Tai’ an city within the scope of coal mine with fully mechanized working face, to fill in the Tai’ an city the blank of fully mechanized coal mining equipment. In learning to grasp the advanced production technology process, forge ahead, continuous innovation, seriously study the new equipment, equipment, in order to seek higher production efficiency.
      The Wang Village in fully mechanized coal process uses the stands, found that the valve set all exposed to external, if because of the unsafe behavior of the people who touch this valve group, it is possible to support action producing an effect to bring security hidden danger. Mineral mechanical and electrical and technology department concerned comrades found this problem, in line with the requirements of the coal mine intrinsically safe, after serious research, invented the valve fully to eliminate the device, the security hidden danger. According to the statistics of the valve, timely and develop the personnel device communication, organization materials, processing, and refine filing patent applications, in the recent smoothly through the state intellectual property office, obtain approval of the patent for utility model, and promote the development of science and technology group company in a new stage.
       And in the first quarter of this year, Taifeng Group to the superior declared “Mine digital wireless mobile video communication rescue system”, and three-dimensional seismic exploration technology research and application in the Lotus piedmont obstacles concentration areas obtained the fine technological achievements in Shandong province, the progress of science and technology offers statistics data for society.
