矿层斜巷中过断层找矿的数学地质研究

Mathematic geological study on locating lost ledge due to fault in incline roadway

原有的过断层寻找断失盘矿层理论的前提是断层两盘产状不发生变化。但实际上,断层两盘产状经常发生变化,此时,根据原理论无法准确确定断失盘矿层位置。本文通过空间几何学方法,研究了断层两盘产状变化条件下,斜巷过断层时两盘矿层的空间关系,并建立了过断层寻找断失盘矿层的数学模型。原有的断层两盘产状不变条件下矿层斜巷过断层寻找断失盘矿层的方法和数学模型均是本文提出的方法和模型的特例。

The premise of conventional theory of locating the missing ledges beyond faults from an opening incline or oblique incline roadways is that the stratigraphic correlations at both sides remains consistent. But practically speaking , both sides of fault are subject to change, by such a theory that , the missing ledge cant be located accurately. Space analytic geometry is used to study the spatial correlations of the ledges on both sides of the faults in incline or oblique incline roadways, and mathematic models of locating missing ledges on conditions that both sides of faults are subject to change. Corresponding to the existing excavated ledges are established. .The conventional method and mathematical model of locating missing ledges from an existing opening in excavated ledges on condition that the stratigraphical correlations of both sides of faults remain consistent can be regarded as special examples of the new method and mathematical model stemming from this paper.
