摘　　要：为降低采区天然焦对煤炭产品质量的不利影响,基于天然焦成因、特性分析,结合矿区井田地质情况和焦化企业对炼焦煤煤质指标的关注重点,济宁七五煤业有限公司统筹兼顾,精心组织生产,通过加强天然焦知识宣教,采取配采、配提、配洗技术方案,在采区局部赋存天然焦的情况下实现了煤炭产品质量的稳定,并确保了炼焦指标的稳定,焦炭强度检测值在二级焦与一级焦质量指标区间,成焦率达到65%以上。济宁七五煤业有限公司煤炭产品质量管理实践不仅实现了煤炭产品质量的稳定,而且有利于促进煤炭及其伴生资源的合理开发利用。In order to reduce the adverse effect on coal product quality brought on by the natural coke incurred in the mining area,Jining Qiwu Coal Co.Ltd.conducted an investigation into the cause of occurrence and properties of natural coke in line with the geological conditions of the mining area and the major indicators of coal product required by the coking sector.Apart from making well-organized mining operations according to the principle of making overall plans and taking all factors into consideration,with the efforts centered on stabilization of output,quality and supply of coal product,as well as strengthening wide publicity of natural coke-related knowledge,other technical measures including mining of coal and natural coke in proportionate manner,blending of coal with the natural coke separately hoisted to surface and washing of coal and natural coke in a blended manner,are also adopted by the mining company.Through adoption of the above going measures,the quality indices of the coke product is stabilized under the conditions that the quality indices of cleaned coal product is adversely affected by the occurrence of natural coke in the mining area.Test data shows what the strength of the coke product lies between the levels of grade I and grade II,and obtained the coke yield over 65 percent points.Implementation of the coal quality management mode has led to stabilized quality of coal product and is beneficial to rational exploitation and untilization of coal and its associated materials.
