Guide: on January 9, it was learned from the Municipal Coal administration that the experimental machine should pay attention to the suitability when selecting accessories. The Zhengzhou small coal mine mechanization development plan was recently issued. According to the plan, before the end of next year, The mechanization of coal mining in small coal mines in the city should reach more than 45%. The plan clearly puts forward that the degree of coal mining mechanization of small coal mines in Zhengzhou will reach the end of 2012

On January 9, it was learned from the Municipal Coal administration that the development plan for mechanization of automatic unloading of small coal overload protection devices in Zhengzhou was recently issued. According to the plan, the mechanization of coal mining in small coal mines in the city will reach more than 45% by the end of next year

the plan clearly puts forward that the mechanization of coal mining in small coal mines in Zhengzhou will reach more than 45% by the end of 2012 and more than 55% by the end of 2015; The mechanization degree of tunneling and loading in small coal mines will reach more than 70% by the end of 2012 and more than 80% by the end of 2015. The drift with the transportation length of more than 1500 meters and the inclined roadway with the vertical depth of more than 50 meters must use machinery to transport personnel

metal spiral pipe JG for prestressed concrete/as blast furnace and reverberatory furnace systems share a set of flue gas absorption system t 3013 ⑼ 4 it is reported that our city has included a number of representative and exemplary small coal mines in the key projects of mechanized transformation to promote the overall progress from point to area; For small coal mines that have the conditions but do not adopt mechanized mining, supporting mandatory measures will be developed to promote
