In recent years，Sunjiacha Longhua m88 best betting website Company is m88 best betting website coal、Drilling、Ventilation、Comprehensive equipment upgrades in transportation and intelligent construction，Total investment more than 800 million yuan，Improved mine production efficiency，Promotes safe production，Laid a solid foundation to achieve “becoming a leading energy and chemical enterprise in the country”。
“Ten million per side per year” becomes a reality
May this year，After multiple rounds of research and technical exchanges，Company’s first set 7.The supplier and delivery period of the 0-meter large m88 best betting website height equipment have been finalized，It is expected to have production conditions by the end of the year。The large m88 best betting website height working face is located in the south of mine 2 level，The recoverable coal reserves are more than 80 million tons，A total of 8 working faces with a length of 4500 meters are arranged，Design service period 10 years。As the fully mechanized m88 best betting website face with the most favorable conditions since the company established the mine，Adhere to high standards from the beginning of design、The principle of strict requirements，Equipped with ZY21000 Zhengmei Machinery Hydraulic Support、Benniu three-machine equipment with installed power of 3×1600kW、Imported Eickhoff shearer、Beijing Haoxinke Pumping Station，At that time，The annual output of one working surface can exceed 10 million tons。
In recent years，The company is working hard on the upgrading and quality improvement of fully mechanized m88 best betting website equipment，The first 400-meter ultra-long working face was mined successfully，Electro-hydraulic control brackets have all replaced manual brackets，Imported coal shearers and imported hydraulic pump stations are very effective in improving coal m88 best betting website technology。After two years of file upgrade，The company currently has 3 sets of 3.0 meter m88 best betting website height equipment，4 sets of ZY10000 hydraulic supports，Coal m88 best betting website face equipment connection is more flexible，The annual production mission support capacity is more sufficient。
Rapid tunneling staged "Fast and Furious"
"Single shift daily footage from the first 10m、20m、30m to now 40m、50m，The excavation speed is steadily increasing，Daily tunneling footage reaches new high。" Feng Yanlong, the former captain of the first excavation team said this。
Early 2021，The m88 best betting website’s first rapid excavation system was successfully installed into the well and debugged，The entire rapid excavation system costs nearly 40 million yuan，Sandvik EBZ670 anchor digger and anchor transporter are used together、Bridge loader and self-moving tail，With one-time lane formation、Safe and efficient、Three major advantages of process simplification，Not only can improve excavation efficiency、Shorten the auxiliary time of anchoring and support，And it greatly reduces the labor intensity of workers。
June 2022，Longhua m88 best betting website Mine Second Set 4.8-meter high-speed excavation equipment has been assembled and debugged，The second set of fast excavation equipment is more advanced and intelligent than the first set，Applied video online monitoring、Advanced detection and three-dimensional geological model fusion technology、Multi-machine collaborative control system、Laser Navigation System、Intelligent excavation technology such as intelligent control platform。At the same time，With dual self-moving tail equipment and kilometer directional drilling technology，Monthly footage can exceed 1500 meters。
Press the "accelerator button" for intelligent construction
Since the completion of the mine 10G industrial ring network in 2020，The m88 best betting website follows the trend，With the goal of accelerating the construction of smart mines，Actively promote the construction of the four modernizations，A breakthrough has been made in automated centralized control。The fourth intelligent working surface is operating stably，Eight main transport belts achieve centralized control，Five underground underground substations、Two central pump rooms、A wind pressure station、Two local ventilation、A temporary drainage point enables remote control and online real-time data monitoring。
This year，The company is making every effort to promote intelligent construction，4G+5G+WIFI6 integrated communication system has been built，Can satisfy big data transmission、Communication and business integration needs。Electronic fence system application successful，Achieved over-limit alarm for underground m88 best betting website working face personnel、Excavation vehicle personnel approach alarm、Two-way alarm function，More safety in m88 best betting website。Mine data center and intelligent dispatching command center、Comprehensive data management and control platform achieves completion acceptance，All monitoring and online monitoring systems are integrated into a comprehensive platform。Currently，4D-GIS Transparent Geological Guarantee System、Main coal flow transportation AI video recognition and monitoring system、Intelligent auxiliary transportation management system、Smart power supply system、Smart ventilation、14 intelligent construction projects including intelligent washing and sorting are progressing steadily。
Permanent magnet drive “plays the leading role”
June，The second set of newly purchased permanent magnet foundation-free belt conveyor at Longhua m88 best betting website Mine has been installed，Debugging runs normally，The underground permanent magnet drive belt conveyor in m88 best betting website mines adds a new member。As of now，Two sets underground 1.4-meter belt conveyors are all driven by permanent magnet motors，1.Belt conveyors 2 meters and below are all equipped with permanent magnet direct drive。Last two years，m88 best betting website mines accelerate the elimination of asynchronous motor + reducer drive method，Continuously introduce permanent magnet drive technology，Make the equipment structure more simple、More environmentally friendly and energy-saving，Can save energy consumption by 3% to 5%，Remarkable energy saving effect，A set of belt conveyor can save 26 electricity bills a year.50,000 yuan。Due to reducing the reducer link，Belt conveyor maintenance costs are lower，Lower failure rate。(Author: Wang Yanbing Editor: Wang Yu)
