煤炭改性优化的开采条件

摘要

In the process of coal resources exploitation,comprehensive evaluation of occurrence lacks,the paper used GIS spatial information technology to achieve quantitative extraction of coal.The method can do quantitative analysis to achieve a maximum amount of coal seams.Variable selection,vector space,attribute information extraction and coal mining conditions can be quantitatively analyzed.A comprehensive evaluation by the discrete smooth interpolation gets the conclusion that except the coal seam thickness and the inclination angle,the number of seam mezzanine is also an important factor for coal mining.The stability degree of seam roof is related to the magma intrusion;the good seam thickness bands,the low dimensional stability is.This study can guide mining engineering layout and provide a reference method for mining design.%针对煤炭资源开采过程中赋存状态综合评价的不足,采用GIS技术进行空间信息的定量提取,实现可采煤层的最大采煤量的定量分析,实现了煤层开采条件的变量选择、矢量空间-属性信息定量提取以及煤层开采条件多变量综合评价的分析.由离散光滑插值建模得出:影响煤层开采的因素除了煤层厚度和倾斜角度外还有煤层的夹层数;煤层顶板的稳定性同岩浆侵入程度有关;煤层厚度较好的条带,其空间稳定性较低.
