元宝山露天煤矿煤质动态预测

Coal quality dynamic prediction in Yuanbaoshan Open-pit Coal Mine

元宝山露天煤矿根据影响煤质发热量的主要动态指标灰分和全水分,推导经验计算公式,预测各平盘、区段煤炭发热量。绘制发热量热值等值线图,并结合各类计划图纸,按规划期预测不同时期的煤质发热量,用以指导生产、销售计划的落实,并为生产经营提供基础分析数据。

According to main dynamic index ash and water content in Yuanbaoshan Coal Mine, the article infers calculating formula of experience, the prediction of flat plate, section coal calorific value, draws the contour map of calorific calorific value.And combining with all kinds of drawings, the mine predicts coal quality heat value according to the different planning period to guide the production and sales, which provides basic data for production and business.
