特殊用煤研究进展及工作前景
|
摘要
基于煤炭地质转型及煤炭清洁高效利用要求的精细化勘查,梳理以往研究中稀缺煤、稀缺煤种、特殊煤、特殊煤种的含义,指出了特殊用煤是基于煤炭清洁高效利用具有特殊工业用途的煤炭资源,其主要种类有液化用煤、气化用煤、焦化用煤以及特殊高元素用煤。本次特殊用煤资源评价以煤岩煤质评价为基础,以煤炭分级分质利用为目标,归纳了特殊用煤资源评价的关键技术指标、经济指标及评价参数,初步提出了基于煤岩煤质特征、资源分布、产业布局的特殊高元素用煤–焦化用煤–液化用煤–气化用煤的特殊用煤评价原则及评价方法,并对晋陕蒙3省的煤炭资源进行了分级评价,统计了75个国家规划矿区液化、气化和焦化特殊用煤保有资源/储量。认为新形势下特殊用煤的研究方向是修改完善煤炭地质勘查规范、制定煤炭利用的分质分级评价标准,按照煤炭利用工艺要求实现煤质和资源的动态评价。
Based on the refined geological exploration of coal, the clean and efficient use of coal, this paper reviews the implications of scarce coal and special purpose coal in previous studies. It was pointed out that special purpose coal is based on clean and efficient use of coal for coal resources with special industrial applications. The main types of coal are liquefaction coal, gasification purpose coal, coking coal and special high-element coal.Based on the coal quality evaluation of coal and the use of coal graded quality, this paper has sorted out the key evaluation indicators and evaluation parameters of special purpose coal. According to coal quality characteristics,resource distribution, and industrial layout of coal and rock in China, the special purpose coal evaluation principles and evaluation methods for "special high-element coal, coking coal, liquefaction coal, gasification coal" were proposed. The paper evaluated the coal resources in three provinces of Shanxi, Shaanxi, and Inner Mongolia, and counted the reserves and reserves of special purpose coal used for liquefaction, gasification, and coking in 75 national planned mining areas. Finally, the research direction of the special purpose coal under the new situation is to modify and improve the coal geological survey specification, formulate multiple quality and grading evaluation standards for coal utilization, and realize the dynamic evaluation of coal quality and resources according to the requirements of coal utilization technology.
