对人们司空见惯的煤炭,如果问你是什么颜色,你一定会回答是黑色或黑褐色。但也不尽然。笔者就曾亲眼目睹过从阳泉丈八煤层中采出的呈红、黄、蓝、紫等色彩斑斓的煤块,俗称“花炭”。最近,黑龙江宝清县,852农场煤矿井下也发现类似的彩色煤块,这种煤呈不规则块状,夹杂在煤层里, If you ask what color you are accustomed to, the coal you are accustomed to will surely be black or dark brown. But not all. I had witnessed the mining from the Yangquan Zhangba seam was red, yellow, blue, purple and other colorful coal, commonly known as “charcoal.” Recently, a similar colored coal block was found in the coal mine at 852 farm in Baoqing County, Heilongjiang Province. This kind of coal was irregularly massive and mixed in the coal seam.
