摘　　要：简述合阳县防虏寨勘查区概况,通过对勘查区煤质化验资料的分析可了解该区煤的煤岩特征、化学性质、工艺性能、煤类及工业用途;区内宏观煤岩类型以半亮型煤为主,无机显微组分矿物质含量较低,有机显微组分包括镜质组和惰质组,其中镜质组以基质镜质体为主;勘查区内煤属于低灰～中灰、低挥发分、中～高硫、特低磷～低磷、较高～高软化温度灰、中高～高发热量煤;煤类以贫瘦煤为主,主要用于动力用煤、民用燃料及火力发电。The general circumstances of Fangluzhai exploration area in Heyang County were introduced,through the analysis of coal quality data of exploration area,the coal petrographic characteristics,chemical properties,technological properties,coal type and the industrial uses of coal in this area could be acknowledged,the results showed that the main lithortype in this mining area is the semi-light coal.Inorganic maceral has low content of minerals,organic macerals are mainly the vitrinite and inert group.The vitrinite is mainly the matrix vitrinite;the coal in the exploration area belongs to low-medium ash,low volatile,medium-high sulfur,extra low-low phosphorus,relatively high-high softening temperature ash,and medium high-high calorific value coal.Meager-lean coal is the main coal type.The main use of coal are power coal,civil fuel,thermal power generation.
