叙述了用判别分析方法对矿井地质构造类型进行预测的原理、方法和步骤。以已采区两个不同构造复杂程度的区域为背景,充分利用钻孔资料提供的信息,以不同抗压强度的岩层厚度、岩性组合等为依据,将主采煤层上下70m范围内的岩层以10m为间隔划分层段,确定地质变量,建立判别函数,定量地给出了小断层存在的部位及其可靠程度,并得到了生产实践的验证。该方法突破了现有的仅用岩层底板标高研究断层的局限姓,得出了矿井构造复杂程度与岩性、岩层组合关系有关的结论,为预测矿井地质小构造开辟了新的途径。
The principle, method and procedure of predicting mine geological structure type by using discriminant analysis are described. Taking the two different structural complexity zones as the background, taking full advantage of the information provided by borehole data, based on the rock thickness and lithology combinations with different compressive strength, the main coal seam within 70m The strata are divided into intervals by intervals of 10m, the geological variables are determined, the discriminant function is established, the existence position of the small faults and its reliability are given quantitatively, and the production practice is verified. The method breaks through the limitation of the existing existing method of studying the faults only by the floor elevation of the rock strata, and draws conclusions about the relationship between the complexity of the mine structure and the lithology and rock formation combination, which opens up a new way for predicting the small geologic structure of the mine.
