Creating a new speed of network mining at the end of 7 hours，Refreshed a new record of 108 stacking brackets arranged in the 60-hour retracement channel，Controlled the penetration error of the top and bottom plates of the retracement channel within 10cm...it only took 5 days，Hanjiawan Coal Company successfully completed the withdrawal task of 213109 fully mechanized mining face，Submitted a satisfactory quick retraction answer sheet。

Behind the string of excellent numbers，It is the majority of cadres and employees of the company who have accelerated，Create a new path，A true portrayal of the new achievements。They used practical actions to shoulder the arduous task of retreating the "Steel Dragon" 100 meters underground，Laid a solid foundation to ensure safe production in mines。

“One side, one strategy，We must fully consider the particularity of the early retreat route of the nose section of the 213109 fully mechanized mining face，Consider the difficulties more fully，Think more deeply about risks，Plan the measures more carefully。”At the 213109 fully mechanized mining face withdrawal mobilization and deployment meeting，Che Chongjie, the warranty leader of the installation team, said firmly。

In the early stage of retracement，Combined with the provisions of "213109 Fully Mechanized Mining Face Retreat Operation Procedures"，The team has prepared coal machine maintenance workers、Scaffolder、Position risk list for M88 login12 types of jobs including belt maintenance workers，List prone risk points and preventive measures，Further enhance risk identification for all employees、The ability to control risks。

Implement double follow-up at the retracement site、Double supervision by security inspectors、Share photos of hidden dangers on site in WeChat group、Three joint reviews of typical accident cases、Dedicated personnel to command important traffic arteries...a series of "customized" safety measures，Ensure that the retracement work standards are not distorted、The work of the personnel in the position does not violate the regulations、On-site hidden dangers will not be dealt with overnight，Provides strong security guarantee for the retreat site。

Play the "Technical Support" march well

Before 213109 fully mechanized mining face enters final mining，The company’s production and geotechnical surveying technology management department deployed this retracement task in advance，Inverted schedule、Flip Chart Operation、Precise force，Use the proficient practical application of the retracement technology under the 3-1 coal geological conditions to plan the layout。

“This retracement，We must play the key role of production technology，Provide supporting technical services for the district team，Make every effort to ensure the safe and smooth progress of the retracement installation task。" said Zhou Zhufeng, director of the company's Production Geometry Technology Management Department。

Drain the accumulated water in the aquifer overlying the working surface in m88 casino reviewadvance、Use periodic pressure to reasonably avoid the pressure impact caused by the overlying rock fracture on the working face support、Calculate the optimal downtime of the production line、Convene a special meeting to arrange for district teams to make connections...under night，In the office of the Production Geometry Technology Management Department，Still brightly lit，Everyone is looking at the drawings，Discuss carefully，Ensure every step of the retracement、Every process is foolproof。

Play the symphony of "United Struggle"

Racing at the same time，Compete with nature，The huge coal shearer drum is gradually peeling off the coal wall between the retreat channel。

"Lower the front roller，Adjust the rear roller a little higher，Pull the first twenty a little further。”Comprehensive Mining Team、The main person in charge of the installation team keeps an eye on the scene，Continuously remind the coal machine driver to achieve precise penetration with the optimal penetration angle and depth of penetration。

When cleaning the floating coal in the channel，Lei Hao, captain of the ambulance squadron, led 23 team members to quickly enter the "battle"。Everyone throw your arms away、Work hard、Work together，Only 3 hours，Thoroughly clean up the floating coal in the machine tunnel，Creating good conditions for the retracement。

“Three retracements、Dismantling equipment，The 22 teammates who came to support this time are really awesome，He helped us a lot in dismantling the equipment..." said Yang Ming, the follower of the installation team。During this retracement，M88 game22 employees supported by the comprehensive mining team，Perfect cooperation with the installation team staff，With familiarity and understanding of 213109 fully mechanized mining equipment，Whether it is disassembling the liquid pipe、Control bracket、Disintegrate three machines，They "won" every task smoothly。(Yang Heng Bai Lele)
