Why is Gulong Coal Mine a regular worker?

As a state-owned mineral, Gulong Mine is a national key construction project developed and constructed by Shandong Xinwen Mining Group Company, with an annual design capacity of 6 million tons/year. The mine field is located in the economically developed area of East China, in Juye County, south-central Juye coalfield, Shandong Province. It is 20 kilometers east of Juye County and 65 kilometers west of Jining City. It is located 40 kilometers west of Heze City.

The mine field covers an area of 180 square kilometers, and there are 6 minable coal seams, of which the average thickness of the main coal seam is 8.82 meters, and the coal types are mainly fat coal and 1/3 coking coal, which belongs to high-quality coking coal with low ash, low sulfur, low phosphorus and high calorific value. The geological reserve of the whole mine field is 654.38+6.83 million tons, with stable coal seam occurrence and simple structure, which is suitable for comprehensive mechanized mining. Mine service life is 82 years. There is a supporting coal preparation plant. Mine for vertical shaft development, * * * set up four vertical shafts (two main shafts, one auxiliary shaft and one air shaft) with a design depth of 840m m ... The total length of mine roadway is 30827 m, and the topsoil sections of two main shafts and air shafts are constructed by direct drilling method, and the topsoil sections of auxiliary shafts are constructed by freezing method, all of which set a national record and fill domestic gaps. The labor efficiency of mine workers is 50 tons/person. The internationally advanced fully mechanized top coal caving technology is adopted, which improves the recovery rate of the mine.
