3month30日，With bursts of roaring sounds，Underground of Northern Shaanxi Mining Hanjiawan Coal Company213109The cut-hole and half-coal rock excavation project achieves comprehensive and accurate penetration，It takes only13Day, another record for the fastest excavation speed was set.
“Is this through the cut eye?”This is the unbelievable reaction of most people after receiving the news。Chang Liangliang, the captain of the continuous mining team, said confidently:“The last full-section penetration time20days,213109Only used for cutting eyes13Oh my god, this is a sudden change in the excavation speed.”
At the beginning of the project, facing213109The tunnel floor is broken、There are cracks in the roof and water is pouring、There is gangue and pyrite and other harsh geological conditions，All cadres and workers of the continuous mining team work hard，Shouted“The digging vanguard team is made through hard work”The strongest slogan.
“The skilled work of the team must be used on the edge，Wooden pillars must be prepared in advance，Drainage facilities must be in place……”The continuous mining team held a timely excavation deployment meeting，Summary of the unfavorable factors encountered in the past tunneling，Overall coordination，Think it all，Detailed division of labor arrangements for work tasks，Fixed the burden of managers。
Organize M88 loginthe formulation of the "Management Measures for Strengthening the Foundation and Improving the Quality of Cut-Eye Working Faces" and the "Measures for the Quality Acceptance and Assessment of Team Projects"，Decompose production tasks to each team，Implement target assessment responsibility system。Within the control distance range，Every increase1mReward team200Work points are formed between teams and groups“Chasing and surpassing”’s good momentum，Greatly stimulated the subjective initiative of cadres and workers。
How to achieve speed? Equipment and facilities are key.“Continuous Mining Machine+Shuttle Car+Double arm anchor drilling rig+Crawler Crusher”No excavation element can be missing。By installing the belt conveyor in the cutout，The shuttle car’s round-trip coal transportation efficiency is improved30%, the excavation cycle progress is improved than before1.5times.
OriginalPDCThe drill bit is drilling holes in the roof support，Frequent drill stuck、Blocked eyes and other phenomena，Time-consuming and laborious。Dong Wenchao, the support worker of the second shift of production, showed his wonderful ideas，Summary of support experience，The reason was found to be the size of the drill bit outlet，Boldly propose to replace coal drill bitsPDCDrill bit plan，Perfectly solves the problem of support constraints，Won the praise of cadres and workers。
How to make“Quick”To“Stable”？Real tricks for risk management。Comprehensive risk assessment of the tasks on duty will M88 gamebe conducted before each shift，Propose preventive measures，Enable employees to take occupational risks and measures into their minds and hearts。Actively organize and carry out“Accident Case Comments”Activities to encourage employees to dare“Take a step”“Open your voice”，From case summary to job extension，Speak out your confidence、Tell me the taste。
In order to reduce the support pressure of large cross-sections, the company organized“Youth Team”Actively carry out on-site hidden danger investigation and use handheld terminalsAPP“Online and offline”Multiple measures have been implemented to implement rectification, and the cumulative total will be57Hidden dangers are nipped in the bud.
Also，Fan Peng, the first production team leader of the continuous mining team, and the team members use the single-arm anchor drilling equipment，To the center line of the top plate528Carry out follow-up support with anchor cables, fully ensuring safe production.
“Record according to the list，It’s time to tighten the swing cylinder of the continuous mining machine，The shuttle car is low on antifreeze……”In order to prevent the occurrence of excavation links“Liewo”Phenomena，Deputy Captain of Mechanical and Electrical Engineering Deng Zhiqi promotes equipment point inspection and maintenance methods，will“Experiential”Promoted to“Listing”, realizing equipment maintenance from emergency“Emergency repair type”Xiang Qianqian“Prejudgment type”Change M88 loginto ensure zero-delay time for cutting-edge excavation.
Meanwhile, the company takes advantage4GAdvantages of full underground network coverage, yes213109HD cameras are installed on the heads of the four belt conveyors on the working surface，Intelligent mining lamps distributed to post workers，Achieved“Visualization+Can call”Effect，On-duty personnel can control in real time on the ground，Ensures the efficient operation of the raw coal transportation aorta，Laid a solid foundation for mine safety production。（Li Jintao）
