关于生产高灰精煤的技术经济可行性研究

Study on the production of high ash coal technical and economic feasibility

良庄矿业的精煤主导产品主要以低灰(8.00%)气煤和气肥煤为主,本文针对目前煤炭市场持续疲软,精煤价格下滑,效益减少的情况,通过对本公司原煤煤质分析,确定生产低灰精煤与高灰精煤的精煤回收率,按照精煤灰分调整前后分品种收入相等的原则计算确定精煤价格,与市场价格相比较,分析了生产高灰精煤的可行性。

Liangzhuang mining coal leading products are mainly low ash（ 8%） gas coal and fat coal,the coal market lasts fatigued and weak,clean coal prices decline,benefits reduced,through the analysis of the coal recovery rate,determination of coal recovery producing low ash coal and high ash coal rate,in accordance with the ash content of cleaned coal sub varieties of income equality principle calculation of coal prices,compared with the market price,analyzes the feasibility of producing high ash coal.
