泥炭是成煤的第一阶段，属于一种年轻的、过渡型的煤．陕南勉县泥炭矿区位于秦岭南坡的勉县县城以北的丘陵区，在地质上呈现一个明显的西北斜带，就其地理位置可分为4个矿体，总括约5km2且具相当蕴藏深度，其中3个矿体整合一体，分布集中．矿样呈灰褐色或黄褐色，疏松易碎，韧性好，具滑腻感，含水量适中，植物残体清楚可辨．泥炭分解程度好，腐殖质含量高，矿质优良．鉴于陕西泥炭开发尚属空白，本研究通过对勉县泥炭资源分布状况的考察，旨在为开发泥炭源，分离提取腐肥等提供一些基本依据．
Peat is the first phase of coal formation and belongs to a young, transitional coal. The Mianxian peat mines in Shaanxi Province are located in the hilly area north of the Mianxian County on the southern slope of the Qinling Mountains. The Moxian County peat mines show a clear northwestern slope in terms of geology and can be divided into four orebodies on the basis of their geographical location, covering a total area of about 5 km2 Depth, of which three ore body integration, distribution of concentrated. Minerals were gray brown or brown, loose fragile, good toughness, with a creamy feel, moderate water content, plant residues clearly identifiable. Peat decomposition level, humus content, mineral quality. In view of the fact that peat development in Shaanxi is still blank, this study examines the distribution of peat resources in Mian County, and aims to provide some basic evidences for the development of peat sources and the separation and extraction of fertilizers.
