由基建工程兵00429部队所属施工部队建成投产的桑树坪煤矿,是我国自行设计、自行施工、自行装备的年产原煤300万吨的现代化矿井。它位于陕西省韩城矿区,井田储量丰富,地质构造简单,可采煤三层,总厚度9.8米,设计储量5.1亿吨,可采120年。该矿是在已开小井群施工的半成品巷道部分刷大利用的基础上扩大井型、由西安煤矿设计研究院重新设计的大型皮带斜井。根据地层自然条件,井田上部的部分煤量用年产90万吨的平峒开采,地面共用一个工业广场和生产系统。投产时斜井的采区设计能力为年产210万吨。20年后平峒采完,由斜井担
The Sangshuping coal mine, built and put into operation by construction corps owned by the infrastructure engineering corps unit 00429, is a modernized mine with an annual capacity of 3 million tons of raw coal designed, self-constructed and equipped by our own country. It is located in Hancheng Mining Area, Shaanxi Province. It has rich reserves and simple geological structure. It has three layers of coal mining, with a total thickness of 9.8 meters and a design reserve of 510 million tons, which can be 120 years old. The mine is opened in a small group of semi-finished products tunnel construction of large part of the roadway to expand the use of large-scale wells, from Xi’an Coal Mine Design and Research Institute redesigned large belt inclined shaft. According to the natural conditions of the strata, part of the amount of coal in the upper part of Ida is mined with an average annual output of 900,000 tons of flat coal, and an industrial square and production system are shared on the ground. Inclined well production area design capacity of 2.1 million tons per year. Twenty years after the flat 峒 mining finished, by the inclined well
