"Good news，Excavation footage exceeded 22 meters in a single shift，The footage exceeded 40 meters in a single day，A new record has been set..." Recently，Good news from the comprehensive excavation team of Hanjiawan Coal Company，During the excavation of 214203 auxiliary transport channel and half coal and rock tunnel，Single shift since the integrated anchor digging machine was put into operation、New record for single-day tunneling footage，Run out of rapid excavation "acceleration"，Sounding the “strongest voice” to stabilize production and supply。
"Currently，The achievement of these achievements，The operation of fast excavation equipment plays a key role。”Deputy Chief Engineer of the company、Introduction by Mr. Kou, captain of the excavation team，"At the same time，We focus on strengthening basic management，Pay close attention to project quality and equipment maintenance quality management，Achieve safe, efficient and high-quality fast excavation。”
As understood，With the continuous advancement of the 214203 auxiliary transport tunnel excavation project，There are many unfavorable factors in the geological changes of the roof，Safety pressure is also increasing。To strengthen safety management、Reduce equipment failures，The comprehensive excavation team held a special meeting M88 appon fast excavation，Comprehensive analysis of problems existing during early equipment operation，Reorganized the responsibilities of all managers and employees in each position、Task redeployment。
Based on various problems that arise during the operation，The cadres and workers of the comprehensive excavation team exert their collective intelligence，Come with ideas、Find a way，Optimize and upgrade the wet dust removal fan installed on the working surface，Adopt long pressure and short extraction ventilation method，Use a combination of soft and hard hair dryers，Reduce dust concentration by 80%，Effectively solves the "stuck neck" problem that restricts the parallel operation of excavation branches。The introduction of two-way material transport trucks solves the problem of long material transport distance on the working surface，Effectively reducing the labor intensity of employees...
In order to continuously break through the "deadlock" of single-shift excavation footage，The comprehensive excavation team replaced the drill sleeve of the windlass digging machine and the anchor transporting machine，Shorten the length of a row of anchor bolts for the anchor bolt digger from the original 5 minutes to 3 minutes，Support efficiency increased twice。In order to control the start and stop of equipment in a timely manner，The comprehensive excavation team uses integrated switches in the production system，The current three belt conveyors can be started in sequence with two centralized controls，Not only ensures safe m88 casinooperation，Saved labor costs again。
Strictly implement "preventive" maintenance of mechanical and electrical equipment，Develop a maintenance plan for electromechanical equipment，Perform maintenance according to the equipment inspection list，And focus on maintenance of core equipment such as tunnel boring machines，Implement charter responsibility system for each equipment，Determine responsibilities for each charter person、Defined standards、Defined tasks，Conduct strict assessment，To ensure the normal operation of each equipment in every shift。
"One month ago，No one dares to imagine that a single class can break through 20 meters of footage。But，Through process improvement and technological innovation，We have set a new record，It can be seen that innovation is productivity、Innovation is combat effectiveness。" Chen Ziliang, Secretary of the Party Branch of the Comprehensive Excavation Team, said excitedly。
Also，In order to mobilize the enthusiasm of cadres and workers to overcome difficulties，In addition to the incentives of the company’s labor competition system per unit of output，The comprehensive excavation team has formulated a stepped footage incentive policy，Clear the production tasks of each team、Maintenance goals and assessment reward indicators，Starting up the competition、Comparison progress、The craze of competition to compare results。
"Refresh of the excavation footage of semi-coal and rock tunnels，Laid the foundation for the company to achieve M88 gameannual production goals。At the same time，It also accumulated valuable technical experience and organizational management experience for the subsequent production of the mine。" Qiao Zhongrang, deputy manager of the company, said。(Author: Chen Ziliang Editor: Wang Yu)
