我国露天煤田分类研究(Ⅰ)——分类指标体系的建立

Study on surface coal fields classifying (Ⅰ)——set up classifying index system

对我国煤田进行大量的调查、统计与分析的基础上,根据煤田的赋存特征、开采条件等建立了露天煤田分类指标体系,分类指标体系由9个一级指标、22个二级指标、71个三级指标所构成.一级指标包括煤田赋存概况、煤岩性质、地表地形、地质构造、水文地质、矿区气候特征、煤质指标、露天煤田规模、矿区周围经济技术条件等9个相互独立的指标.建立了分类指标的量化模型,并对各种不同的分类指标取值进行标准化处理.

Founded a surface coal fields classifying index system basis on coal field feature and mining condition by investigating and statistics and analyzing. This classifying index system are composed of 9 first-level indexes, 22 second-level indexes and 71 third-level indexes： The first-level indexes include 9 independent indexes that are the general situation of coal field existing, coal and rock property, topography, geological construct, hydrological geology, climate of mine region, coal quality, size of surface coal field, economic and technological conditions of mine region. The numeral model of every classifying index was established, and the classifying indexes were treated with standardization the value.
