Recently，The Shaanxi Provincial Energy, Chemistry and Geology Union commended the advanced models of Shaanxi’s energy, chemistry and geology system in 2023。The mechanical and electrical maintenance class of the comprehensive mining team of Hanjiawan Coal Company won the honorary title of "Worker Pioneer" of Shaanxi Energy Chemical Geology System。

There are currently 33 employees in the mechanical and electrical maintenance class of the comprehensive mining team of Hanjiawan Coal Company。In recent years，Mechanical and electrical maintenance class adheres to "high standards、The work philosophy of “strict requirements”，Pay close M88 loginattention to employee skills training，Open "WeChat Mini Classroom"，Carry out master-apprentice training、Organize job pairing training and other activities，And pass one question per day、One case per week、Monthly exam and case analysis、Safety prediction and pre-control work，Help employees accumulate safety production knowledge。The electromechanical maintenance class also seriously implements "one-to-one"、Two to one” pair learning method，Strive to train every employee into a technical generalist。Three people have passed the advanced professional skills appraisal，9 people passed the intermediate professional skills appraisal；1 employee won the third prize of Comprehensive Mining Maintenance Electrician in Shaanxi Province’s first “Sanqin Craftsman Cup” Staff Vocational Skills Competition。

October 2022，Due to geological changes during the final mining period of 214202 fully mechanized mining working face，More than 1 meter of gangue appears on the working surface，Resulting in slow production progress。All members of the electromechanical maintenance class faced the difficulties，To the shearer、Hydraulic support、M88 gameThree machines、Increase maintenance of electrical equipment，Focus on solving problems such as how to break gangue on the working surface。After more than 10 days of joint efforts，Successfully completed the penetration mission，Creates good conditions for installation retracements。

The electromechanical maintenance class also establishes and improves innovation effectiveness guarantee，Encourage all employees to continue to innovate。2022，Completed coal shearer with loader remote control、Inverter cooling water circuit modification、30 innovative projects including belt self-moving machine tailstock modification，Effectively reduces the labor intensity of front-line workers，Achieved economic benefits of more than 7 million yuan。A ventilator protection device、5 items including controllable fan blades and windshield adjustment，obtained national practical patent certificate。(Liang Xiaohu Du Xueli)
