Dong Suizhi, 37, graduated from the Engineering Surveying Department of Resources and Surveying Department of Chongqing Engineering Vocational and Technical College in 2005. He joined the Communist Party of China in 2010 and has been awarded the "Excellent Communist Party of China" by Nantong Coal Mine Model Workers and Models. "Chongqing Coal Mine Safety Supervision Bureau Yunan Supervision Branch Bureau" and other honorary titles, in June this year, was named "Excellent Communist Party Member" by Chongqing Energy Group.
Dong Suizhi grew into a deputy chief engineer of drainage prevention from the technicians of the geological survey department of Nantong Coal Mine, the host of the geodesy survey department, the technicians of Tongwaco, the deputy chief of Tongwaco ventilation, the deputy chief of extraction, and the chief of anti-outbreak. Footprints left a trail of flashing struggle.
After graduating from school to work in Nantong Coal Mine, Comrade Dong Suizhi deeply felt his lack of abilities, and there was still a big gap in the use of knowledge in books, so he secretly resolved to become a leader in his work. Dissatisfied, he often uses the rest time to combine his doubts at work with the theoretical knowledge he has learned, pondering over and thinking carefully, and often asking leaders and colleagues with an open mind.
"He often holds a book at night, sometimes with his eyes closed and contemplative, sometimes using a pen to sketch, and rarely goes to bed before 12 o'clock in the evening." His wife Yu Wanying understood her husband's work very well.
Hard work pays off. Through hard work, Comrade Dong Suizhi has developed a strong business ability, which is deeply appreciated by the leaders and colleagues of the mining science team.
Lead the way
"Every job I do my best, and deserves my responsibilities!" This is the philosophy of Comrade Dong Suizhi. He has been working for 14 years, based on his post, charging ahead, and working hard.
In June 2018, in the process of coal mining at 6 levels of Shimen at the negative 450 level, Dong Suizhi often worked overtime, abandoned bed and night, and actively gave up his rest time. He successfully completed the hydraulic fracturing construction drilling design, safe and reliable coal mining measures, and technical measures. Immediately after passing the leadership review, personnel of relevant sections and teams were organized to conduct in-situ hydraulic fracturing, gas pre-drainage, supplementary drilling through layers, and use "blocking, intercepting, and pumping" techniques to control gas.
After eradicating the “roadblocker” of gas, he went deeper into the front line, coordinating, directing, organizing, inspecting ... doing not miss every small link, regardless of fatigue, fear of hardships, nervous and orderly busy, moving, moving Colleagues and co-workers around. The safe coal mining has created good conditions for gas management in the 5th floor of the mine and deployment of the 6th floor mining area.
Dedicated to success
"Love is my duty, and dedication is my duty!" This is the motto of Dong Suizhi. From September 2008 to March 2011, in the 1.2 million tons of technical renovation and expansion project construction of Nantong Coal Mine, Dong Suizhi successively completed the estimation of the third-level belt conveyor error, the design of the construction measurement plan for the third-level belt conveyor project, and the control and construction measurement. The control and construction survey of the gangue belt conveyor have been verified by experts to meet the safety requirements of the coal mine, and have achieved accurate penetration, which has made a great contribution to the construction of Nantong Coal Mine's first million-ton main coking coal mine in Chongqing.
From January to December 2012, in the construction of the national gas demonstration mine, Dong Suizhi participated in the completion of the mine geology chapter, the completion report of the gas treatment demonstration mine, and the technical summary report in the construction plan of the gas treatment demonstration mine with high inclination and low permeability. , And successfully passed the acceptance of the national expert group.
In gas management, he and engineering technicians successfully developed advanced gas management technology achievements such as "pre-draining pre-drained gas long boreholes" and "outburst prevention technology in fully mechanized mining face in dangerous areas", and created the "before mining The new comprehensive situation of comprehensive management of pre-drainage through layers, pre-drainage in this floor, and pressure relief drainage in this layer and adjacent layers. The application of these scientific and technological achievements enabled the mine to eliminate coal and gas outbursts and explosion accidents.
