摘要：

安徽省含山县陶厂石膏矿资源储量大，石膏质量较好，但石膏层的化学组分在垂向上及横向上有较大变化。为了研究矿石品位的分布，对陶厂石膏矿首采区硬石膏的井下钻孔、巷道以及采房取样，测试了硬石膏中SO₃、CaO、MgO含量及烧失量（LOSS），并分析了各之间的关系。分析结果表明：首采区-400 m水平矿石SO₃含量由底到顶有降低的趋势；随着CaO含量的增加,SO₃含量明显增加；随着MgO含量的增加，样品的烧失量增加。首采区-400 m水平矿石品位变化原因一方面与沉积相的变化有关，另一方面与地质构造有关。

Abstract:

Taochang gypsum deposit, located in Hanshan county, Anhui province, has a large resource and better quality, but largely variable in chemical components both vertically and horizontally. This paper aims to study the grade distribution, takes samples in drilling holes, galleries and rooms, and measures SO₃, CaO, MgO and LOSS in anhydrite, and analyzes their relations. The results show that at -400 m level in the first mining face SO₃ falls upward, rises with CaO, LOSS rises with MgO. The reason of grade change lies in the sedimentary facies and structures.

Key words: first mining face, anhydrite, grade, reason
