The first modern coal mine in Guangxi has been built with an annual output of more than 1 million tons of raw coal

the first modern coal mine in Guangxi was completed and put into operation in Baise. After nearly a year of production and operation, the comprehensive mechanized coal mining and tunneling productivity efficiency has increased by more than 10 times compared with the past, so that a small coal mine with an annual output of more than 100000 tons has rapidly developed into a large mine with an annual output of more than 1 million tons of raw coal; Automatic information monitoring also provides a solid guarantee for the safety production of high-risk coal industry

Guangxi reported that Baise Mining Bureau, the implementer of this high-tech coal production project, has the courage to innovate development ideas, dare to break the traditional old thinking that "the underground hydrology in the south is developed, and the geological structure is complex, which is not suitable for fully mechanized mining and fully mechanized excavation. First, enhance the technological development and utilization capacity of non-ferrous materials, and enter the production process". Since 2005, it has invested more than 100 million yuan to transform and upgrade its donghuai coal mine with an annual output of more than 100000 tons, Promote comprehensive mechanized coal mining and tunneling; After several months of installation and commissioning, the standardized and normalized joint test run began in May last year. Now as long as the operator gently presses the button, with the roaring and rapid rotation of the serrated wheel, the coal pours down the coal wall and flows to the ground with the belt conveyor. Mechanized coal production has not only greatly reduced the labor intensity of coal miners, but also achieved high production efficiency for most of the utilization of high molecular polymers: the coal mining efficiency has increased from 2.5 tons per worker in the past to 32 tons per worker, up to 44 tons; The average daily output of coal is more than 3000 tons, and the maximum daily output is more than 4000 tons, making the annual raw coal production capacity of donghuai coal mine, a small mine with 500 employees, exceed the million tons mark, which is equivalent to the coal production scale of a mining bureau with 5000 or 6000 employees in a traditional mining process

at the same time, donghuai coal mine is equipped with an automatic safety production information monitoring system, so that the underground gas, coal dust, air volume, hydrology and the production process of the mining face can be sensitively and quickly reflected on the television screen of the ground dispatching center through remote sensing, and the production commanders can timely understand and master the situation of each link and make decisive treatment. In the past year, donghuai coal mine has not had a safety production personal injury accident, nor a mechanical, fire, gas and other disasters

fully mechanized mining and fully mechanized excavation is an exploratory and pioneering work in southern China. Director ye Fangyong led the leadership of Baise Mining Bureau. After a lot of investigation, research and demonstration, and engineering technology, from an international perspective, personnel and workers practice and explore at the same time. After a tortuous process of frustration, summary, improvement, stability, maturity and standardization, donghuai, a modern coal mine, finally achieved success. Huang Wenbiao, director of Guangxi Coal Safety Supervision Bureau, said with deep feeling: it's really unexpected that Baise Mining Bureau has transformed and upgraded donghuai mine into a modern mine in such a short time with amazing boldness and courage, and has become a model mine in the whole Guangxi coal industry. This has set an example for Guangxi coal mining enterprises and made a significant contribution to the scientific and technological progress of Guangxi coal mines and the realization of coal mine safety production and high-efficiency production. Zhao Lianjing, a national fully mechanized mining expert, said that with geological conditions such as donghuai mine, the implementation of fully mechanized mining and fully mechanized excavation can be successful in a few months, which is rare in peers across the country, and its production technology is advanced in peers across the country

Baise Mining Bureau, which has tasted the sweetness and gained experience, is now starting to transform nahuai coal mine and Dongsun coal mine, which are undoubtedly huge business opportunities, into a modern coal mine with fully mechanized mining, fully mechanized excavation and automatic safety information monitoring. At the end of this year or next year, Baise Mining Bureau will develop from an annual output of 300000 tons of coal in the past to a "three high and one good" Modern Mining Bureau with an annual output of 2.5 million tons, which has high technology content, high production efficiency, good safety production and high staff quality of life
