The new infrastructure helps the mine upgrade, and the era of smart mines has arrived

By the end of 2019, intelligent mining has been tested and produced in major coal producing areas in China, and has been applied in more than 200 working faces in Yankuang, Shendong, Ningmei, Zhongmei, Shaanxi Coal, Tongmei, Yangmei, Pingmei, Jinmei, Fengfeng and other mining areas. The intelligent mining technology of Tiandi technology is applied to the first intelligent coal mine in China, and the intelligent system of fully mechanized mining equipment developed for the first time is promoted and applied in Huangling No. 1 Mine, which realizes the "working face patrol and unmanned operation; Visual control along the channel, remote coal cutting on the ground "; The number of production workers on the working face decreased from 11 to 3, and the production efficiency increased by 25%. In 2019, the State Coal Administration issued the "Catalogue of Key Research and Development of Coal mine Robots", which clearly will vigorously promote the less humanized and unmanned coal mine field operations.

2.2 Eight ministries and commissions issued policies to indicate the direction of the industry

On March 2, 2020, eight ministries and commissions including the National Development and Reform Commission jointly issued the "Guiding Opinions on Accelerating the Intelligent Development of Coal Mines" (hereinafter referred to as the "Opinions") to promote the integrated development of intelligent technology and the coal industry and improve the intelligent level of coal mines. "Opinions" proposed to encourage financial institutions to increase support for intelligent coal mines. Encourage enterprises to initiate the establishment of relevant market-oriented funds to form a long-term mechanism to support the intelligent development of coal mines.

(1) The implementation of the Opinions is divided into three stages

The "Opinions" proposed that by 2021, a variety of types and different models of intelligent demonstration coal mines will be built, and a technical system of information transmission and automated operation for major links such as coal mine development and design, geological support, production and safety will be initially formed. Basically realize the reduction of workers and improvement of efficiency in the driving face, less human or unmanned operation in the fully mechanized mining face, unattended and remote monitoring of fixed posts in underground and open-pit coal mines. By 2025, large coal mines and coal mines with severe disasters will basically realize intelligence, form a technical specification and standard system for intelligent coal mine construction, realize intelligent decision-making and automated collaborative operation of systems such as development design, geological support, mining (stripping), transportation, ventilation, washing and logistics, and robot operation of key underground positions. Open pit coal mines realize intelligent continuous operation and unmanned transportation. By 2035, all kinds of coal mines will basically realize intelligent energy, build a multi-industry chain and multi-system integrated intelligent coal mine system, and build an intelligent coal mine system with intelligent perception, intelligent decision-making and automatic execution.

(2) The Opinions put forward ten major tasks

Including strengthening top-level design, scientific planning of intelligent construction of coal mine; Strengthen the guidance of standards, improve the basic ability of coal mine intelligence; Promote scientific and technological innovation, improve the level of intelligent technology and equipment; Accelerate the intelligent transformation of production coal mines and improve the intelligent level of new coal mines; Play the role of demonstration and drive, build intelligent demonstration coal mine; Implement the construction of green mine and promote the coordinated development of ecological environment; Promote the application of new generation information technology, and build intelligent platforms at different levels; Explore new service models and continue to extend the industrial chain; Speed up the training of talents and improve the ability of personnel support; We will strengthen international cooperation and actively participate in the construction of the Belt and Road Initiative.

(3) The "Opinions" proposed deep integration with modern information technology

The "Opinions" proposed that all departments should speed up the construction of smart factories and digital workshops, promote the research and development and industrial application of large coal machine equipment and coal mine robots, implement special actions of mechanized replacement and automation reduction, and improve the integration and localization level of intelligent equipment. It is necessary to accelerate the promotion and application of modern information technologies such as industrial Internet and Internet of vehicles, new generation communication technologies, cloud computing, big data, artificial intelligence, and virtual reality in the coal industry. It is necessary to build a new industry of research and development and manufacturing of coal mine intelligent equipment and coal mine robots, and build an influential intelligent equipment and robot industrial base.
