“Why are the picks of the cutting drum worn like this。”Looking at the cutting drum of the continuous mining machine that was delivered after the well was lifted，Xi Qiangqiang said sadly，“I’ll try to repair it with a welding gun，There is no need to ask the manufacturer to replace it”。

Just do it，Xi Qiangqiang took the welding gun，Control the temperature carefully，Weld it carefully。The missing pick was repaired bit by bit，After the repair welding, he polished the repaired picks smoothly，A repaired cutting drum soon appeared in front of everyone，Reassembly and trial operation are normal。After a period of use，No abnormality in the feedback from the production class，Everyone gave a thumbs up to Xi Qiangqiang’s skills。

Xi Qiangqiang is an employee of the continuous mining team of Hanjiawan Coal Company，Not only good in technology，There are more golden ideas，As a technical "master"，He especially likes to speculate on waste materials，affectionately called "Xi Nengneng"。

Underground support workers of the continuous mining team during the support process，Water from the roof will wet the work clothes。For this，The district team is equipped with anti-splash raincoats for each support worker，But since there is no fixed storage location for raincoats，After the shift change, raincoats often get lost or are scratched and damaged when placed elsewhere，Not just a waste，Also affects production。

See this phenomenon，Xi Qiangqiang pondering，Can you make a raincoat storage device，Can hang a wet raincoat。This idea runs through his mind every day，He also carefully considered and researched this。

After many communications with colleagues in the production class，He used angle steel and drill pipe as a shelf，Use iron sheet to install water protection shed，Welded anti-splash raincoat hanging device。The supporting workers who took over took over the raincoats directly at a fixed location，Saves time，Improved work efficiency，It can also extend the use time of the raincoat，Created convenience for colleagues in the production class。“Now you no longer have to worry about finding a raincoat，It has to be ‘Xi Neng Neng’！" Support worker Jia Xianlin said happily。

October last year，Continuous mining team 223102 is in the process of opening the excavation working face，Because the m88 casino reviewshuttle car’s pressure chain plate has not been replaced for a long time，And more wear and tear，Cause the pressure chain plate to break during use，Affected excavation production，Due to the deformation of the pressure chain plate and the number of chain links，Welding is difficult，Everyone has a headache about this。

At this time，Volunteer，After discussing with everyone in the maintenance team，Decided to lift the shuttle car into the shaft first and remove the pressure chain plate，Use the secondary protection welding method for welding。With his unremitting efforts，The m88 casino reviewshuttle car’s pressure chain plate was welded soon，Using super technology to make "significant contributions" to the safe production of the district team。

Crawler crusher cooling and dust reduction device、Anti-spraying device for electric control box of crawler crusher、Shovel storage device... each innovation makes "Xi Neng Neng" "famous"。Due to outstanding performance，He has been awarded the company’s Maker Expert、Youth Technical Star、Honorary titles such as advanced individuals in energy conservation and environmental protection。

“I was trained in the mines，Also gave me honors and awards，This is not only trust but also encouragement and motivation，Only if you do a good job，Only then can I have a clear conscience。m88 casino”Speaking of which，Xi Qiangqiang, who has always been unsmiling, turned serious，That determination，No doubt。(Huang Jieheng)
