江苏省基本建设公司承担三河尖矿井的施工任务,我们五处担负地面建筑及井上、下主要设备安装工程。三河尖煤矿是一座年产原煤120万t矿井,1988年8月投产。 三河尖矿整个建井过程可以看作是一个完整的系统工程。其中,主副井筒施工——大巷贯通——副井永久装备——主井永久装备是矿井建设的关键路线(主要矛盾线)。这条线控制了矿井的总工期,因此,这条线上各工序的进度快慢,工序之间衔接紧凑与否,工序顺序是否合理,直按影响到矿井投
Jiangsu Provincial Capital Construction Company undertakes the construction tasks of the Sanhejian Mine, and we are responsible for the construction of the ground and the installation of major equipment at the site of the well. Sanhejian Coal Mine is an annual output of 1,200,000 tons of coal mines, put into operation in August 1988. The whole process of well construction in Sanhejian Mine can be regarded as a complete system engineering. Among them, the main shaft and the auxiliary shaft construction - through the main road - permanent auxiliary shaft - main shaft permanent equipment is the key construction line (the main line of contradiction). This line controls the total duration of the mine. Therefore, the progress of each process in this line is fast, the cohesion between the processes is compact or not, the order of the processes is reasonable, and the direct injection affects the pit casting
