“25212 The console device M88 appcannot connect to the Internet，Automation equipment is not running，Find me a manufacturer now。”“Don’t worry, don’t worry，It will take half a day for the manufacturer to arrive，Go directly to the Zhiwei Center to find our comprehensive mining master--He Jiafei。”This is a scene that happened at the fully mechanized mining face of Hongliulin Mining Company。
M88 game
Thoughtful，Excellent professional skills，Work with quality，Management methods... Speaking of He Jiafei, the person in charge of comprehensive mining at Hongliulin Zhiwei Center，Everyone can name many adjectives，But，More people are willing to call him "Master"。Experienced, he has installed 14 intelligent fully mechanized mining working faces，In the National Coal Industry Employee Skills Competition in June 2021, it won the honor of winning the Bronze Award for Comprehensive Collection and Work Control。
From the first day of working in the Intelligent Management Center in 2015，He Jiafei focuses on his work，His first task is the unattended transformation of two substations。After more than a month of hard work，The person on duty is on the centralized control computer in the office，You can realize remote power outage and power supply for underground equipment，The substation has since started manned inspections、The unattended "new era"。
Early 2016，Due to the need to build “three types and four modernizations” mine construction，25207 Intelligent fully mechanized mining working face installation kicked off。
Time is tight、Heavy duty is the characteristic of this job，Production facing the working surface、The dual challenge of simultaneous maintenance work and project construction，M88 appHe Jiafei and his colleagues worked overtime、Forget about food and sleep，Working all night is commonplace。Check information online、Read related books、Ask the manufacturer’s technicians... They use all the resources at their disposal to improve themselves。
They gave up with their families、Opportunity for family reunion，Running around in the dormitory、Restaurant、Underground，These three points and one thread connect their entire lives。Solve the problems one by one，Overcoming difficult problems one by one，They have successively completed the preparation of system technical specifications、Trial，Install together with the contractor、Debug，The transformation was finally completed successfully，Remote manual intervention control of coal machinery is realized、Advanced automation control of coal shearers，And real-time monitoring of various data signals of coal shearers。
The vanguard army that overcomes difficulties
Although the transformation is completed，But there is still a tricky process that needs to be solved - the laying of optical cables in the shearer drag chain。Due to the large mining height of the working face，The film gang is serious，The coal machine roller throws coal during the coal mining process，In addition to factors such as frequency-sensitive bending of the towline chain，It is easy to cause injury or damage to the optical cable。He Jiafei led his colleagues to study carefully，Thinked of dozens of solutions，But none of them are ideal。
Later I saw a high-pressure liquid pipe on the working surface，He Jiafei had a sudden thought，If the optical cable is inserted into the high-pressure liquid pipe，The problem of optical cable protection m88 casinowill be solved。But new challenges arise，High pressure liquid pipe has higher hardness，In the limited space within the drag chain，Laying is more difficult。
In order to strive for early operation，All optical cables、Wires and equipment were carried by M88 appHe Jiafei and his colleagues、Carry on the shoulder，The entire working surface is covered with their sweat。Laying more than 15,000 meters of communication optical cable，Installation bracket controller、Automatic backwash device、Infrared receiver, etc. 204，and 522 various sensors、108 high-definition network surveillance cameras...after 4 months of continuous hard work，August 8, 2016，Project construction is finally completed，August 9，The system is officially put into trial operation。
When all signal data are displayed normally on the computer display of the ground intelligent centralized control center、Transmission，When the system is first tested，Applause、The cheers rang out，Pride and smiles fill the faces of M88 appHe Jiafei and his colleagues。
Technology "Master" with a vision for the future
"When you know that Northern Shaanxi Mining will establish an information technology operation and maintenance branch，I was the first to sign up，Because I think I will have a broader platform here。”Whenever I talk about my original intention of joining the information technology operation and maintenance branch，He Jiafei is always filled with emotions。
The Information Technology Operation and Maintenance Branch is a research and development company、Design、Supervision、Construction、A professional technology company integrating operation, maintenance and training，Integration、Integration、Innovation and unlimited development prospects，m88 casinoIt is He Jiafei’s choice without any worries。
"Although the work is very hard，But the company provides everyone with a platform suitable for their own development，We find a sense of belonging and a source of motivation here，This is a stage where one’s own value can be reflected。”
Talk about future development，He Jiafei said that he must first comprehensively improve his personal business level，There is still a lot of fully mechanized mining equipment and related knowledge that I need to constantly update and learn at work。Secondly，Break old work ideas、Abandon "etc.、The thought of relying on”，Do your own thing，The team rushes to do things。(Author: Qiao Jiao Wang Yaowu Editor: Wang Yu)
