The open-pit mining of refractory clay deposits is mainly carried out by mechanized zoning mining. The interior of the stope is developed by a return-type route. The stripping adopts the parallel working mode of the working face, using mechanical chiseling blasting. The blasted ore is loaded by electric shovel and transported by car. At present, many non-key mines or townships and towns mining mountains use manual blasting, car or manual transfer.
The underground pits of refractory clay deposits are mostly developed by inclined wells, belt conveyors or electric winches to raise ore and transport by car. In order to ensure the mining according to the grade, every 5m excavation in mining, often take a chemical sample on the face to analyze to determine the boundaries of the grade.
Refractory clay mining
China's refractory clay deposits are divided into two types: mining and pit mining. Part of the open mining - pit mining combined. The key mines of Lu Cai are Shanxi Taihu Quarry Mining Area; Henan Jiaozuo Datun and Moshipo Mining Area; Inner Mongolia Zaihuaigou Mining Area, Guizhou Xiaobaoba Mining Area; Guangxi Hepu Bainikeng Mining Area; Shandong Ziboluo Village Mining Area, and so on. The key mines in the pit mining are Shandong Hongbo Mining Area and Dongbaoshan Mining Area; Jilin Shulan Huqu Liu Mining Area; Sichuan Miyi Ertan Mining Area; Henan Jiaozuo Shanglizhuang Mining Area and so on.
