    The reporter learned from the Anhui Provincial Intellectual Property Office that a patent led by Yuan Liang, an academician of the Chinese Academy of Engineering, recently won the 15th China Patent Gold Award, which achieves the purpose of "coal and gas co-mining" by providing the best environment and conditions for coal mining, and eliminates the gas threat
    in a large area.

    The reporter learned that China's coal mine geological conditions are special, the structure is very complex, the gas content is high and the permeability rate is low, it is difficult to extract the gas before mining, therefore, it is easy to have accidents such as gas explosions in coal mining
    .
    How to extract gas before coal mining to achieve safe production has always been a major problem
    plaguing China's coal mining industry.
     
    The patent "Method for Extracting Pressure Gas from the Roof of the Y-shaped Ventilation Goaf Area along the Empty Lane Left Alley" led by Academician Yuan Liang takes into account the safety technical problems such as gas treatment, coal mining, and face cooling, solves the problem of corner gas accumulation on the coal mining face, improves the recovery rate of coal resources, and directly utilizes the extracted high-concentration gas, realizing green mining
    .
    At the same time, it has created a precedent for comprehensive gas treatment technology services and become a key technology
    for coal and gas co-mining promoted by the whole industry.
     
    It is reported that up to now, the technology has been applied and promoted in more than 200 working faces under similar conditions in similar mining areas in Anhui, Huaibei, Tiefa, Xishan Coal Power, Huajin Coking Coal, Shaanxi Coal Chemical Group, etc.
    , covering a production capacity of more than
    800 million tons.
     
    Academician Yuan Liang said that before the implementation of the technical plan, the number of deaths due to coal gas accidents in China was about 4,000 every year, and after the technology was promoted, the number dropped to about
    350 last year.
