Research and practice of intelligent-green mining in the billion-ton mine cluster of Shendong Mining Area

In order to achieve safe, intelligent, efficient and green mining in the billion-ton mine cluster, Shendong relies on technological and management innovations, develops a new intensive production model, forms the world's first billion-ton mine cluster, and sets up an advanced model of modernization and development of the coal industry for the coal industry. Based on this, the scientific and technological innovations developed by Shendong in the past ten years for the billion-ton mine clusters are systematically introduced: In terms of safe production technology for ten million-ton mine cluster, it has developed the peripheral rock control technology for the extra-high comprehensive mining face, adopted the directional drilling hydraulic fracturing technology to soften the hard rock layer on the roof, developed and promoted the coal pillar-less mining technology to realize the safe mining of the coal seam cluster in close proximity and the coal seam in composite areas, developed the mine pressure early warning platform to realize the safe mining under the water-rich roof slab. In terms of intelligent and efficient mining technology for billion-ton mine cluster, Shendong has developed complete sets of equipment and technology for 8.8 m large-height comprehensive mining face, developed double-channel fast-digging technology and process system, innovated equipment and technology for inclined shafts constructed by the full-section shield method, and researched and developed mechanized mining technology for short-walls and contour-type coal-mining technology for thin seams, which has improved the efficiency of digging, and it has innovated an intelligent transportation system, formed intelligent mining technology with automation of following machines, remote intervention, intelligent coal cutting (memory coal cutting, predictive coal cutting and autonomous coal cutting) and intelligent linkage of cables as its core features. It has constructed a billion-ton intelligent coal processing plant demonstration site in Shangwan, and formed a planning framework for the comprehensive construction of intelligent coal processing plants in Shendong mining area, and formulated the data communication standard of “data interface and protocol for mining equipments”, For the first time, it proposed and realized the concept of “one network, one station” system construction, and taken the lead in introducing the Hongmeng operating system for mines, built a 100 – million – ton intelligent production control platform. In terms of green mining technology for billion-ton mine cluster, it has constructed an ecological environmental protection and restoration technology system, developed microbial ecological restoration technology and multi-dimensional waste reuse technology, and built a number of national ecological restoration demonstration bases, realizing the coordinated development of ten million tons of resources and the environment in the mine cluster. In terms of comprehensive management technology for billion-ton mine cluster, it has established a comprehensive management system integrating quality (work quality, service quality, management quality), safety, health, environmental protection, etc., formed an advanced comprehensive management technology in the coal industry, which plays an important role in the production and operation of ten million-ton mine cluster. The research results provide a reference for the coal industry to realize independent innovation, and play a positive demonstration and leading role in the planning, construction and development of large-scale coal bases in China.
