Railway Construction Technology in Henan province coal excavation support
Recently, the project of railway construction heavy industry in cooperation with the Central South University of the shield type bolting machine key technology research "by the Henan Provincial Department of science and technology and good access to key support project.
"The key technology research of shield type excavating machine" is aimed at the implementation of coal excavation. It is reported that coal and iron and steel are the basic basic energy in China, which account for about 70% of the primary energy structure, providing favorable support for Industry and so on.
During the 12th Five-Year, the coal made a lasting progress, but there was a problem of imbalance and unsustainability in the process of development. Long term coal mine construction, resulting in coal mining speed is far behind the speed of mining, mining unbalance.
At present, the roadway excavation equipment to the main excavation digging machine, machine imported, bolting work division of work, can not be completely synchronized, anchor operation time is far behind the driving speed, the overall efficiency is hard to improve, it is difficult to break 700 meters per month.
"Shield tunneling machine project" Research on key technology of anchor excavation equipment of large coal roadway through the overall integration of manufacturing technology, the synchronous control technology of bolting, drilling advance prediction technology in tunnel construction, real-time detection and early warning technology of coal mine explosion-proof technology equipment and harmful gas cutting device, a roadway design technology. Dig anchor machine online and dust ventilation equipment cooling technology, the key technology of intelligent guidance technology, the development of a long wall coal mining to adapt to domestic construction efficiency, safety and environmental protection of the shield type bolting machine, realize "will explore a dig, dig anchor will be harmful dredging, synchronization, safe and efficient", will to improve the efficiency of coal mine roadway excavation per month more than 3000 meters, and improve the construction environment, to fill the gaps in the field, the implementation of the project will effectively solve the long-term constraints of coal mining "imbalance" The difficult problem is a revolutionary change in the construction of coal mines, which is of great significance for improving the independent innovation ability and international competitiveness of China's high-end equipment manufacturing industry, building the high-end equipment industry chain in the province and promoting the overall technological progress of the underground tunneling equipment industry.
It is reported that, according to the relevant requirements of Hunan Province, foster the development of strategic emerging industries, strategic emerging industries in projects to focus, strengthen innovation, two types of lead and pragmatic "principle, focusing on advanced equipment manufacturing, new materials, cultural creativity, biology, new energy, information, energy saving and environmental protection and other seven areas. After the project reporting, expert evaluation, comprehensive defense, field investigation departments, the provincial government approval, the final legislation in Hunan province strategic emerging industries advanced equipment manufacturing projects the focus of support.
