On January 8th, at the National Science and Technology Awards Conference, the China University of Mining and Technology, together with its partners, developed the "Safety, High-efficiency and Fine-fine Blasting Technology and Equipment for Coal Mine Roads" and won the second prize of the National Technology Invention Award. Filled another gap in the national science and technology awards.
In 2014, the professional equipment company and the provincial enterprise technology center cooperated with the innovation team of Yang Renshu, the president of China University of Mining and Technology (Beijing), to undertake the research and development of deep hole blasting equipment in coal mine roadway, and successfully developed coal mine in 2016. Drilling (anchor) units with rock tunnels.
In August 2016, after the coal mine rock-filled (anchor) unit was used in the coal mine trial, the R&D team improved the product. In May 2017, through trial use, the trial results reached various indicators of fine blasting. From October 2017, the coal mine rock tunnel drilling (anchor) units have successively been in Weibel Coal and Electricity, Huaibei Group, Yongmei Group, Yimei Coal Collector, Henan Coking Coal Group, Zibo Coal and Electricity Group, Shenhua Ningmei Group, 16 coal mine groups such as Yonggui Energy Group, Yangmei Group, Tongmei Group, Pingmei Group, Xishan Coal and Electricity, Yanhe Energy Group and Sichuan Coal Group are promoted or tried.
The coal mine rock tunnel drilling (anchor) unit adopts remote intelligent remote control operation, and the coal tunneling is safe, fast, and efficient. The coal mine working face is reduced by more than 60%, and the production efficiency is increased by more than 50%. The coal mine rock tunnel drilling (anchor) unit has 6 invention patents and 15 utility model patents, which fill the gaps in the domestic industry and have been included in the National Coal Mine Safety Supervision Bureau to promote new products. In 2018, the newly-added sales revenue of coal mine rock tunnel drilling (anchor) units was more than 86 million yuan. At present, the supply of products is in short supply.
