摘要
运用趋势面分析、变异系数及可采率指数等数学地质方法对平山湖井田7-2号煤层厚度变化规律进行分析,为以后的矿井生产提供地质依据。
By using the mathematical geology methods of trend surface analysis , variation coefficient and recoverable rate in-dex, the variation regularities of №7-2 coal seam thickness in Pingshanhu Mine were analyzed .The research results can provide geological basis for mine production later .
