府谷县位于陕西省的最北端,府谷县是全国罕见的矿产资源富集区,被誉为“黄河金三角”,是国家在本世纪末下世纪初能源建设战略西移的重点开发区。目前已探明的煤炭地质储量为200多亿吨,主要由侏罗纪和石炭二迭纪两大煤系构成,具有储量大、煤质好、易开采、煤层埋藏浅、层位稳定、瓦斯低或无瓦斯的特点,地质构造简单,可露天、斜井、平硐等方式大规模开采,是世界七大煤田之一。煤质具有“三低一高”特点,即特低灰(5.3—7.36％)、特低硫(0.36—0.87％)、特低磷(0.002—0.025％)、高发热量(6952—7438大卡/千克)。高岭土矿和石炭二迭纪煤共生,已探明储藏面积120平方公里,储量3.59亿吨,中试煅烧主要技术指标为:
Fugu County is located in the northernmost point of Shaanxi Province. Fugu County is a rare mineral resource-rich area in the country. It is known as “Golden Triangle of the Yellow River” and is a key development zone where the country moves its energy construction strategy to the west by the end of this century. At present, the proven geological reserve of coal is more than 20 billion tons, mainly composed of two major coal measures of Jurassic and Carboniferous-Permian. They have the advantages of large reserves, good coal quality, easy exploitation, shallow coal seams, stable bedding, Low or non-gas features, simple geological structure, open-pit, inclined shaft, adit and other means of large-scale mining, is one of the world’s seven major coal fields. Coal has the characteristics of “three low and one high”, ie ultra low ash (5.3-7.36%), extra low sulfur (0.36-0.87%), extra low phosphorus (0.002-0.025%), high calorie (6952-7438 kcal /kilogram). Kaolin ore and coexistence of Permian coal, proven reserves of 120 square kilometers, reserves of 359 million tons, pilot calcination of the main technical indicators are:
