3D engineering display of low seam longwall coal mining technology

HOT can help you to maximize ore reserve value basis on our operating expertise
We have years of underground mine engineering and operating experience and across multiple commodities using all common mining methods.
Especially, we have many successful design and operation experiences for underground coal mines those are thin coal seam, large dip angle, as well as many faultags. And most of these coal mines (thin coal seam) are designed and operated by longwall mining method (fully mechanized mining). The thin coal seam longwall method helps to satisfy the highest safety standard and more margins.
● Large dip angle, thin coal seam longwall（dip angle range: 35°-55°）
● Thin coal seam, very thin coal seam longwall（Thinnest seam range: 0.8m ~ 1.3m）
