贵州省煤炭资源有效保障能力分析

Analysis of Coal Resource Effective Supply Ability Based on Grey Clustering in Guizhou Province

利用灰色聚类分析和层次分析等数学方法,建立了煤炭资源有效保障能力分析的数学模型,分析了贵州省煤炭资源有效保障能力。结果表明:贵州煤炭资源保障能力的基本态势是总量丰富,但有效供给能力不足。省内已发现资源的开采年限可达111a,但受限于资源特性和可采性,发现的资源/储量有效保障能力相对不足,净有效量确定的保障年限为45a,当前可供净有效量确定的保障年限仅为30a。

Through the use of grey clustering and analytic hierarchy process, established a math model for coal resource supply ability analysis and analyzed the Guizhou Province coal resource effective supply ability. The result demonstrated that the basic situation of supply ability is abundant gross amount and insufficient effective supply ability. The exploitation life of known coal resources can be 111 years as long, but is subject to resource peculiarity and mineability. The effective supply ability of known reserve/resource is relatively insufficient, secure exploitation life of net useful quantity is 45 years, while current available net useful quantity is only 30 years.
