Stone Coal Machinery R&D Project won the second prize of Hebei Science and Technology Progress Award

It was recently learned that the project "Stone Drift Rapid Excavation Technology Research and Development of Complete Sets of Equipment" independently developed by Shiji Coal Mining Co., Ltd. and possessing independent intellectual property rights was recently awarded the second prize of Hebei Provincial Science and Technology Progress Award in 2012 by the Hebei Provincial People's Government. The acquisition confirms that the company has occupied a new commanding height in the field of technology research and complete equipment manufacturing in the field of rapid excavation in Yanxiang, and has the value of promotion.
The low efficiency of rock lane development is one of the bottlenecks restricting the rapid production of coal mines. In particular, how to improve the development efficiency of hard rock roadway in middle and above grades has become an urgent problem for the coal industry. The company has many years of experience in researching and developing rock tunneling equipment and has undertaken two key projects for the National 863 Program for roadheaders. Based on its own advantages and combined with the cutting-edge technology of rock lane development, the company has optimized the design of the excavation equipment for the problems existing at home and abroad. The company has adopted the longevity of the public and developed the requirements to meet the requirements of modern mines. Rock tunnel rapid excavation technology and complete equipment". The project differs according to the rock hardness of different coal mine rock lanes. It is difficult to completely solve all the problems of rock lane development in one scheme. At the same time, considering the economy of development, two solutions are designed to solve the problems of different rock lanes. . One of the solutions was the research and development of the EBH300(A) cantilever rock tunnelling machine, which solved the development of rock lanes with medium rock hardness. The second option is to research and develop a rock lane operation line composed of hydraulic drilling rigs, side unloading vehicles and skid-mounted machines to solve the rock rock lane development with higher rock hardness. The major coal mines can choose different sets of equipment according to the actual conditions of their own roadway to form an efficient rock tunnel development plan.
The project has been applied in large-scale coal mines such as Shandong Xinwen Mining Group and Fengfeng Group, which has increased the drilling footage of rock lanes to more than 2 times that of traditional technology, greatly alleviated the problem of misalignment in the coal mines, increased the production efficiency, and improved the roadway efficiency. high quality. The application of the project satisfies the needs of modern mines for efficient and safe production, which has effectively promoted the development of coal mine rock lanes to fully realize mechanization and completely solved the difficulties in the development of rock mine lanes in coal mines. It is a technical revolution in the development of rock lanes. (This article comes from a stone coal machine)
