"What，He is on board for support？”“Impossible，I don’t believe it...” In the continuous mining team of Hanjiawan Coal Company，Producing a class of college students Li Jiancheng relies on his own efforts，Refreshed everyone’s knowledge，The growth rate of the "rookie" in tunneling is "stunning"。

August this year，A young man from Anhui came to the continuous mining team，Become a part of the district team family。One meter eight tall，Baby fat face，Always speak softly。“So far away from home，Can Southern children adapt to this coal mine？”This is a common problem for everyone in the district team。

Graduated from Xi'an University of Science and Technology，But he did not regard it as his own "aura"，But continue to m88 bet hard to enrich yourself。"Deploy air bag、Clamp the nasal congestion，Turn the oxygen valve counterclockwise..." at the pre-shift meeting，His proficiency in operating and demonstrating the self-rescuer is comparable to that of an experienced veteran employee。

It is time for the district team to construct the 223102 working face opening project，Wide area、Many tasks，High security pressure。"Every time you comment on the accident case video，He is always the first to come on stage，And the reviews are very good，Something exciting。" Squad leader Fan Peng said。

Post reflective paper、Clean up floating coal、Suspension cable... sweating profusely，He never tires of it。Li Jiancheng quickly stood out among college students，Taken into the position of crusher driver。

“If you want to do it, do it at the core，I want to get on the four-arm anchor drilling rig，I want to m88 bet as a support worker。”Half a month later，After passing the practitioner examination，He helped prepare support materials from the beginning，Be familiar with various types of anchor rods and cable models，More than board the double-arm anchor drilling rig，Assist in supporting the anchor rods in the tunnel，Know a complete set of support techniques by heart。

"Tap-tat-tat..." Rotate the small handle、Observe the pressure gauge、Zero position closing valve，An anchor cable was successfully tensioned。"As his master，I was worried at first，Now the opposite，This is a helper sent to me！" Support worker Zhang Haiwei said with satisfaction。

“There is a big brother in the team、There is a story，I want to write them out。”Active guidance through the branch，Manuscripts such as "Old Scalper" and "There is Such a "Red Squad Leader"" were published。In his writing，The seemingly ordinary but real team is perfectly presented in front of everyone。

What is subjective initiative？The company has just concluded the third quarter correspondent training course，While everyone is still on the way to complete the task of "revealing the list and leading the questions"，He has already taken the initiative to choose the topic and completed the writing。The manuscript of ""Three Good Prescriptions" to Build a 100-Day Safe Production Barrier" is newly released。When asked how to write a comprehensive manuscript，He smiled and said: "The road is under the nose，Ask！”

Because I can do whatever I want，Can endure hardship、Love learning，A “rookie” from the beginning，The “little expert” till now，Li Jiancheng is working steadily on his own growth path，Use practical actions to shine in the district team。(Li Jintao)
