掘进工作面隐伏构造预测系统的研究与应用

Research and application of buried structures prediction system in driving working face

对掘进工作面地质构造预测进行研究,采用三角网插值方式,通过多种常用的插值算法,拟合构造影响下的不连续煤层(空间)形态。在拟合煤层底板形态的基础上,利用数学地质中统计分析方法及时发现掘进工作面当前的测量点异常,借鉴有掘必探工作中的钻探及物探成果辨别异常存在的真伪。同时建立识别各种构造的数学模型,根据已有的区域、煤田、井田构造特征及发育规律分析引入专家判别经验值,因地制宜确立参数,通过异常发现和异常判别实现隐伏构造的定量预报,为矿井地质工作者矿井小构造综合评价和预测提供依据。

In order to research geological structure prediction in driving working face, triangulation network interpolating method was used with many common interpolation algorithms to fit discontinuous coal seam（space） form under structure influence. On the basis of fitting seam floor shape, statistical analysis method in mathematical geology was applied to discover current abnormal measuring point in driving working face, together with taking drilling and geophysical prospecting results of distinguishing unusual existence authenticity as example. Meanwhile, mathematical model of recognizing various structures was established, expert discrimination empirical value was adopted according to structural feature and developing law analysis of existing area, coal field and well field, adjusting measures to local conditions to set parameters. The quantitative forecast of buried structures realized by anomaly detection and anomaly criteria provided reference to mining geologist with comprehensive assessment and forecasting about minor structure in mine.
