【正文】 I 煤炭資源的真三維評價 摘要 影響煤層開采的條件有多種因素，本研究從煤層地質賦存狀態(tài)來評價影響煤層開采的綜合條件。煤層資源開采條件的綜合評價有利于從總體來設計開采區(qū)，合理布置采礦工程，提高煤炭的開采回收率，提高生產效益。 煤層開采條件包括煤層的厚度，埋深，傾角，煤質，頂?shù)装鍘r性，煤層中的夾層厚度和數(shù)量，構造應力，巖溶積水，巖漿侵入對煤質和煤層的破壞，后期河道沖刷對煤層的改造，斷裂切割對煤層的破壞，煤層的連續(xù)性等多種因素。 借助 GIS 技術，分別對上述因素進行空間信息的定量提取，對各個可采煤層進行綜合定量評 價，利用三維可視化技術對煤層分布和影響開采的各種因素進行顯示。可以合理指導煤炭的有序生產，保障煤礦生產安全 [1]。 關鍵詞：煤炭資源，綜合評價， GIS，三維 II TRUE THREEDIMENSIONAL EVALUATION OF COAL RESOURCES ABSTRACT Coal mining conditions affecting a variety of factors, from the coal geology of this study to assess the impact of existing state coal mining in general terms. Coal resources, mining conditions conducive to the prehensive evaluation of overall mining area to design, reasonable layout of mining engineering, coal mining to improve recovery, improve production efficiency. Coal mining conditions, including coal seam thickness, depth, dip, coal, roof and floor lithology, seam thickness and amount of dissection, tectonic stress, karst water, magma intrusion on coal and coal seam damage, erosion of the river late the transformation of coal seam, breaking the destruction of coal cutting, coal seam continuity and other factors. With GIS technology, these factors were the quantitative extraction of spatial information, each coal layer on a prehensive quantitative evaluation, using threedimensional visualization of the distribution and impact of technology on coal mining display a variety of factors. Reasonable guide to the orderly production of coal, coal mine production safety protection.
