基于Surfer的复杂煤层赋存规律分析

新疆焦煤(集团)有限责任公司一九三〇煤矿5号煤层赋存不稳定,运用传统的三点法确定复杂煤层赋存规律存在局限性。为准确掌握煤层赋存规律,选用Surfer软件进行分析研究,通过插值方法优选,确定利用克里克方法进行等高线预测,利用多元回归法进行产状分析。研究表明:5号煤层存在小区域构造变化;基本产状为264°∠22°;斜风井迎头至煤层顶板法向距离为5.8 m。该研究结果为下阶段石门揭煤提供了准确详实的参考资料。利用Surfer软件分析复杂煤层赋存变化规律,快捷直观。

Analysis on Occurrence Pattern of Complex Coal Seam Based on Surfer

The occurrence of No.5 coal seam in 1930 Coal Mine of Xinjiang Coking Coal(Group) Co.,Ltd is not stable,and the traditional three point method has certain limitations to the determination of the occurrence pattern of the complex coal seam.In this paper,the authors conducted the study and analysis on the occurrence of the seam by using Suffer software,predicted the contours through the optimization with interpolation method and by using Kriging method and analyzed the occurrence of the seam by using polynomial regression method in order to accurately understand the occurrence pattern of coal seams.Study showed that there was a small regional structure change in No.5 coal seam;the basic occurrence was 264°∠22°;and the normal distance from the heading face of the inclined airshaft to the seam roof was 5.8 m.This research result provided accurate references for exposing outburst seams in a crosscut at next stage.The use of Surfer software to analyse the occurrence pattern of complex coal seams is quick and intuitive.
