Overview Jizhong Energy Co., Ltd. Xing Dong mine is located about 4km northeast of Xingtai City, convenient transportation and strategic location. With a designed annual output of 600,000 tons, after a series of technological transformations, the approved production capacity in 2009 was 1.25 million tons / year. At present, the mining depth is close to -1200m, making it one of the largest mines in North China. The main technical features of concrete-filled steel tube supports 1. The structural features of concrete-filled steel tube supports The concrete-filled steel tube supports are the modern components filled with concrete in the steel tube shells. The concrete filled steel tube members have a cylindrical shape, which is the most scientific and rational cross-sectional shape, Stiffness, no anisotropy, no
