The mining techniques of alabaster mine, ordinary gypsum mine and anhydrite mine are similar. The room and pillar mining method (generally 8-12 m in width) and breasting method are adopted. The drilling of gypsum ore is easy, but the explosive consumption is large, generally 0.34 kg/t.
Furthermore, gypsum is a mineral in global demand (Herrero, Escavy, & Bustillo, 2013), and its extraction by mining inevitably damages valuable gypsum habitats (Chapin, Sala, & Huber-Sannwald, 2001; Mota, Sánchez-Gómez, & Guirado, 2011). Thus, mining companies are usually compelled to conduct restoration programmes despite the lack of ...
Gypsum is a non-metallic mineral, found in rock form. It is composed of 79.1% calcium sulphate and 20.9% water, by weight.
