Hanjiawan Coal Company uses "learning regulations、implementation、Strong Management” activity is the entry point，Actively promote the “1+4” quality improvement model，Produced and distributed 840 copies of the "Disaster Prevention Knowledge Handbook"。Promote the "dispatch will draw back" system，Give full play to the "head goose effect"，Managers at all levels “take the lead in learning、Take the initiative”，Standardization knowledge level has been significantly improved。

Strictly implement the “test must be taken every time you check”，Organize and carry out "standardized computer-based exams" every quarter，Layered coverage，A long-term mechanism for learning and assessment has been formed。Follow "Please come in、Principle of “Going Out”，Invite experts to the mine regularly for training，1,623 people participated in quality improvement training。

Steady creation to promote the standardization project，Hanjiawan Coal Company m88 online sports bettinguses 2.Version 0 Double Prevention App Platform，Set up "risk、Hidden dangers and personnel positioning linkage real-time push” function，Making employees "walking underground"，Current Risk、Push the hidden dangers there”，Effectively improve the level of safety production standardization。

A heavy blow to paint the "standard background color"

Hanjiawan Coal Company actively promotes the “1248” safety production standardized management system，Taking the “Four Demonstration” projects as the starting point，By setting a "timetable、Roadmap”，Strive to create 213110 high-quality excavation working face、3-1 Coal Quality Distribution Chamber and a series of "2468" quality projects，Continuously expanding the high-quality demonstration area，The battle for high-quality system demonstration has begun。

Faced with problems such as potholes on roadway concrete pavement，The company paved asphalt and sprayed white walls on the main auxiliary transportation alleys underground，The total length is 4860m。2-2 Coal auxiliary transportation lane ditch and cover renovation 1200m，Ensuring the smooth flow of the mine’s auxiliary transportation arteries。Resolved 3-1 coal、4-2 Stubborn problems such as the chaotic laying of 2600m cables in the coal auxiliary transportation lane，Make the cables hang neatly and uniformly。

Carry out timely work to control hidden disasters，Comprehensive cleaning of the underground 2-2 coal return air alley、Reinforcement support m88 live casino and sports bettingand road hardening，Resolutely raise the standard to the level of "the return air can flow smoothly"。Brainstorming，Strive to create a “2+4=N” standardized chamber，2-2 Coal extends to 2 pump rooms in the 4-2 Coal system、All 4 water silos have achieved standardized and dynamic compliance。

Benchmarking practice polishes the “innovation background”

Close to the “nose” of safety production standardization innovation，Encourage employees to strive to be "pioneering cattle" in innovation and development。Actively build a mass entrepreneurship and innovation studio for model workers、Maker Station and Maker Factory，Continuously promote the implementation of innovative results。Driven by innovative work，Hanjiawan Coal Company has obtained 61 national utility model patents，More than 350 important innovation achievements。

Five innovative achievements, including "An Automatic Traction Device for Comprehensive Excavator Pipeline" and "Remote Unmanned Automatic Air Volume Measurement Device and System for Coal Mine Lanes" won the third prize in the 2021 Shaanxi Provincial Enterprise "Three New and Three Small" Innovation Competition award。Condensed and formed the "Best Innovation Practice Results of Intelligent "110" Construction Method for Medium-Thick Coal Seams in Northern Shaanxi Mining Area"，Innovated more than 30 best application technologies such as top cutting and blasting。

Meanwhile，The company organizes professional and technical personnel to go out for benchmarking study，Compared m88 casinowith advanced mines 10 times in total。By "bringing in、Self-conversion” method，Comprehensively promote the application of new equipment such as mechanical explosion-proof devices，Innovatively completed more than 20 achievements including "Optimization of Tunnel Excavation Support"，Created economic value of more than 40 million yuan，Making the "dividends" brought by innovation truly implemented in the work of safety production standardization。(Author: Wang Shuai  Editor: Wang Yu)
