Case analysis of major meteorological disasters, mine tailings dam, 2008 September 8, Xiangfen County, Linfen City, Shanxi Province, the new tower Mines Ltd. Tower Hill iron ore tailings children due to flash floods, resulting in significant storage capacity exceeding dam The tailings sand loss is about 2× 10 6 m3, the flow length is 2 km, the maximum width is 300 m, and the mud area is 30.2 hectares, resulting in 277 deaths, 34 injuries, and 1047 people affected by the dam failure.

Fused magnesia is mainly made of magnesite with 47% content and fused in electric arc furnace. The chemical indexes of fused magnesia can be divided into six major items. 1, Magnesium Oxide content; 2. Silica content; 3, iron oxide content; 4, aluminum oxide content; 5, caustic soda; 6, body density; Fused magnesia products have high purity, large crystal particles, compact structure, strong slag resistance material, good thermal shock stability, is an excellent high temperature electrical insulation material, is also an important raw material for high-grade magnesia bricks, magnesia carbon bricks and amorphous refractory materials.
