The "dafabet login muscle" for delving into technical problems - Liu Xiaolong from Pulongwan Coal Industry of Shanxi Coal International

Liu Xiaolong is the second-level specialist of Pulongwan Coal Industry Production Technology Department，From a front-line worker in the comprehensive mining team to a technician in the production technology department to a second-level specialist in the production technology department，He has been strict with himself for more than ten years，Dedication，Based on your own position，Study hard on technology，Bravely shoulder the heavy workload。“Very persistent in technology，I like to think about everything，Somewhat ‘dafabet login muscle’。” is the evaluation of him by his colleagues。Everyone has become accustomed to his busy figure，With his solid professional knowledge、Rich front-line work experience and serious and rigorous work attitude，Won unanimous recognition and praise from leaders and colleagues。At the Second Second Session of the Seventh Shanxi Coking Coal Workers’ Congress and the 2023 Work Conference，Liu Xiaolong was named the first "three-year, three-step" level two meritorious individual。

Be brave in dafabet login and dare to take on heavy responsibilities

At the beginning of the establishment of Pulongwan Coal Industry Technology Innovation Center，Faced with staff shortage、Difficulties such as weak technical strength，Liu Xiaolong under the leadership of the chief engineer，Working on the front line。From passive learning to active acquisition，Continuously improve dafabet login’s professional level and innovation ability at work，Carry out technical research on weak links in production safety，Realized the effective transformation and application of scientific and technological achievements。

dafabet login day，Liu Xiaolong discovered during underground on-site observations and conversations with underground workers，When the gangue layer on the working face is thicker and stronger，The gangue layer may be exposed or the lumps may be larger after being broken, which may affect coal placement；The participation of the gangue layer reduces the crushing effect of the upper top coal，Thus affecting the recovery rate；For China、Lost in trouble，The top coal below the gangue layer is thin，Especially when the mining height is large，Its stability is reduced，May affect normal production。He kept these in mind，After research、Argument，Think that by optimizing the mining process design of top coal caving in thick coal seams，Can further improve top coal caving recovery rate，Played a positive role in safe and efficient production。From this，He actively participated in the project "Research on Technology for Improving Top Coal Recovery Rate of Mechanized Caving Working Faces under the Condition of Multi-layer Gangue Entrainment in Thick Coal Seams"，Lead technicians to analyze and verify the hydraulic fracturing caving technology of thick coal seams containing multiple layers of gangue。Through numerical simulation、Experimental research and field testing，Analysis shows that thick coal seams under multi-layer gangue conditions，Deformation and failure mechanism of coal and rock structure，Mastered the instability characteristics of top coal in fully mechanized caving mining、Strength characteristics and deformation characteristics。On this basis，Combined with field test，The formation of hydraulic fracturing caving technology and technology for thick coal seams containing multiple layers of gangue，Applied in the 5# coal seam of Pulongwan Coal Mine，And achieved good results。

Every effort is rewarded。Liu Xiaolong’s participation in these years、Declared more than 60 scientific and technological innovation projects，More than 30 minor reform projects，has been rated as "advanced worker" and "scientific and technological innovation pacesetter" many times。He and professional technicians are based on actual production needs，Continuously explore technological innovation projects，Overcame dafabet login technical problem after another，Contributed to Pulongwan’s scientific and technological innovation work。

Diligent, studious and thoughtful

As a technician working from the grassroots level，Liu Xiaolong is always hungry for knowledge，Cherish every training and learning opportunity，And come back with a full load every time。Since joining the work，He insists on actively learning and mastering new technologies、New Standard、New process，Think carefully and summarize based on reality，Understanding in practice。Sometimes we encounter complex problems，I’ve spent a lot of effort but still can’t figure it out，He asked people dafabet login by dafabet login with questions，Until the problems are solved dafabet login by dafabet login。

Study dafabet login and improve your skills

2021，Liu dafabet login takes charge of mining、dig design work。At first，He is not familiar with these jobs，But with his unyielding character，Frequently go underground to record technical parameters，Review the designed drawings、Check calculation，Go to other mines to benchmark and learn，Think deeply about the design intention。After coming back，Following the construction status again，Discover problems in time、Solve the problem，Continuously accumulate design experience，Rapidly grew into an expert。

According to the group company’s comprehensive promotion of “dafabet login excellence and three reduction” work requirements，Liu Xiaolong pondered over the layout of the mine，Optimize the layout of the 52 mining area，Refined working surface layout，Reasonably arrange production connection，Breaking through the mining bottleneck。He optimized the design of the 5105 working surface，Leave openings in available system lanes，5105 two straight slots use 5103 system lane，Ensures the smooth flow of the transportation system while reducing the excavation footage of the working face system lane，Saving cost about 1 million yuan。He actively participated in the promotion of the "Six Elites" work at the 5111 work surface，According to layout location characteristics，Optimize transportation system，Construction and moving joint lane from auxiliary transportation lane，Reduce moving transportation distance by 240m，Improved moving efficiency，Shorten the moving time by 10 days。In design，Liu Xiaolong completed the 5111 working surface、5105 working surface design，Prepare 2 working face mining designs，More than 160 local tunnel designs，Ensuring the normal connection of mine mining。

When people talk about his achievements，Liu dafabet login always says，Achievements only belong to the past，Focus on the future，We must, as always, persist in the fine style of hard work，Provide "hard" support for mine safety production，Contribute to the development of Pulongwan Coal Industry with practical actions。
