How intelligent can workers be in mining nowadays? The upgrade of surface coal mining from remote ground control to intelligent planning and cutting is another significant progress! "" By performing simple planning operations on the ground, various underground comprehensive mining equipment can complete complex coordination operations, and the integrated control platform is very advanced and practical! "Recently, at the 20th China International Coal Mining Technology Exchange and Equipment Exhibition China Coal Science Exhibition Area, Such exclamations are constantly present among the exhibition audience. The reporter learned that China Coal Science and Industry Group released a complete set of solutions for unmanned intelligent mining control technology in coal mines at the exhibition. According to this plan, surface coal mining can be upgraded from previous remote ground control to intelligent planning cutting. This means that mining workers can carry out simple planning operations on the ground, allowing various underground equipment to complete coordinated operations; The operators in the office don't even need to stare at the screen for a long time to achieve the ultimate goal of "unmanned coal mining". According to the introduction, this technological achievement aims to achieve unmanned coal mining with the goal of unmanned entry into the combined operation area of the coal mining machine, scraper conveyor, and hydraulic support during the coal mining operation of the fully mechanized mining face. The innovative unmanned mining control technology scheme of "planning coal cutting+visual remote intervention" is proposed. Based on highly reliable comprehensive mining equipment, R&D personnel have developed technologies such as coal mining process driving engine, planning and cutting control, intelligent video recognition, and integrated support technologies and equipment such as inspection robots, individual equipment, and fault diagnosis. They have also newly developed an integrated "immersive" remote mining control platform, And a demonstration project of a new unmanned intelligent mining model with "ground planning coal mining, automatic equipment execution, and unmanned operation in the face" has been established, which has been operating normally for more than 6 months. According to the introduction of China Coal Science and Technology Corporation, the unmanned coal mining new mode of "ground planning coal mining, automatic execution of equipment, and unmanned operation in the face" has achieved a normal unmanned entry of the joint operation area of the coal mining machine, scraper conveyor, and hydraulic support during the production of the demonstration working face, and the production efficiency has increased by 16.7% compared to on-site operation with personnel. This scheme adopts the coal mining process driving engine technology in the fully mechanized mining face, achieving flexible coal mining process planning, adjustment, and online switching, meeting various operation scenarios, and achieving a 100% collaborative operation rate between equipment. A new method for planning and cutting control of coal mining machines, with an effective cutting template rate of over 95%. The cutting height control accuracy can reach 3cm. It is reported that this technological achievement has been applied in Shendong Yujialiang Coal Mine and Huangling Mining No.1 Coal Mine, achieving continuous industrial application of unmanned working faces during production, and the coal mining efficiency has been significantly improved compared to traditional models, providing an empirical and normalized application solution for unmanned coal mining in fully mechanized coal mines. At present, this technology has been promoted to Yangcun Coal Mine, Binhu Coal Mine of Shandong Energy Group, and Jiayang Coal Mine of Sichuan Coal Group. In addition, China Coal Science and Technology Corporation has teamed up with Huawei to release a "full series of intelligent safety individual equipment for the mining industry", creating a unified entrance and business platform for super miners, and achieving interconnection and intelligent collaboration of "people, machines, environment, and equipment". Among them, the KT618 (5G) - S2 mining intrinsic safety mobile phone is a Mate60 series certified for coal safety
