马槽滩磷矿含磷层假整合于震旦系上统白云岩古喀斯特凹凸侵蚀面之上,矿体厚度直接决定于古地形。采用回归法分析了矿体厚度与古地貌之间的关系,据统计研究,矿体厚度属随机变量。矿区深部构造为一系列走向北东,平行于主褶皱的次级褶皱。次级褶皱的发育使含磷层上升于侵蚀面之上,从而有利于开采。根据地质特点,对矿区外围远景作了预测,勘探结果已初步证实其可靠性。
The phosphorus-containing layer of the mashuitan phosphate rock is falsely integrated with the karst erosion surface of the Upper Sinian dolostone. The thickness of the ore body is directly determined by the ancient terrain. Regression analysis of the relationship between the thickness of the ore body and paleogeomorphology, according to statistical studies, ore thickness is a random variable. Deep mining area is constructed as a series of secondary folds to the north east, parallel to the main folds. The development of secondary folds causes the phosphorous layer to rise above the erosion surface, thus facilitating mining. Based on the geological characteristics, the prospect of the periphery of the mine area has been predicted. The exploration results have initially confirmed its reliability.
