一、概述 保和堂矿区位于湖南省中部的邵东县境内。区内的含煤地层为龙潭组,厚约200m,含煤四层,下部两层一般不可采,上部两层为可采煤层,分别均厚0.60和1.19m,其元素组成及工艺参数等见表1.由表1可以看出,保和堂煤(以下简称保煤)为一种低灰、特低硫、特低磷、富油及高发热量的优质煤。其煤岩及热解性质较独特。 I. Overview Baohentang mine is located in Shaodong County in central Hunan Province. The coal-bearing strata in the area are Longtan Formation, with a thickness of 200m and four coal-bearing layers. The lower two layers are generally not recoverable, and the upper two layers are recoverable seams with an average thickness of 0.60 and 1.19m respectively. The elemental composition and process parameters See Table 1. As can be seen from Table 1, Baohe Tang Coal (hereinafter referred to as coal) is a low-ash, extra-low sulfur, extra-low phosphorus, rich oil and high-calorie high-quality coal. Its coal rock and pyrolysis properties are more unique.
