受湖南省沅陵县人民政府的邀请,石煤协会派出石煤综合利用技术专家组有关专家对沅陵石煤开发利用技术进行咨询服务。专家组通过实地考察、审阅有关技术资料,并认真听取了各方面意见,经过全面分析讨论,从该县实际情况出发,提出了《关于湖南省沅陵县石煤开发利用的咨询意见》。沅陵县是湖南省最大的山区县,水路交通四通八达,为经济发展提供了方便条件。该县石煤资源丰富,远景储量达5亿t。据白雾坪0.4km~2普查报告,C+D级储量达379万t,含V_2O_5平均0.938％,平均发热量为4855J/g,平均厚度19m。据中国地质大学对该处含钒石煤的试验研究,在最佳钠化焙烧条件下(900℃,90min),转化率可达67％。
Yuanling County, Hunan Province by the invitation of the People’s Government, Stone Coal Association sent a comprehensive expert group on the use of coal-related experts on the Yuanling stone development and utilization of technology consulting services. Through field visits, the expert group reviewed relevant technical information and listened attentively to opinions from all aspects. After a comprehensive analysis and discussion, starting from the actual situation in the county, the Group put forward the Consultative Opinion on the Development and Utilization of Stone Coal in Yuanling County, Hunan Province. Yuanling County, Hunan Province is the largest mountain county, waterway transportation extending in all directions, providing a convenient condition for economic development. The county rich in stone coal resources, long-term reserves of 500 million t. According to the survey report of Baifengping 0.4km ~ 2, the C + D reserves reached 3.79 million tons, with an average of 0.938% of V2O5, with an average of 4855 J / g and an average thickness of 19m. According to the test conducted by China University of Geosciences on vanadium-containing stone coal, the conversion rate can reach 67% under the optimal sodium roasting conditions (900 ℃, 90min).
