伟晶岩脉和产在其中的白云母矿体(以下简称矿体)向深部延伸的形态和产状都是比较复杂的;矿体两侧边界线(指在纵剖面上的,以下同)的产状也是多种多样的。因矿体的形态和产状是受储矿构造控制的。并与矿区地质构造有密切关系,所以矿体的形态和产状仍有一定的规律性。通过勘探和开采,发现许多矿体是側伏延伸的(以下简称侧伏)。在勘探和开采过程中要重视矿体侧伏的研究。只有弄清矿体的侧伏,才能合理地布置勘探和开采工程,多快好省地查明矿体、提交储量和合理开采。
The pegmatites and the muscovite ore bodies produced therein (hereinafter referred to as the ore body) extend to the deeper forms and occurrences are more complex; border lines on both sides of the ore body (in longitudinal section, the same below) The appearance is also varied. Due to ore body morphology and occurrence is controlled by the deposit structure. And is closely related to the geological structure of the mining area. Therefore, the shape and appearance of the ore body still have certain regularities. Through exploration and exploitation, many ore bodies are found to extend laterally (hereinafter referred to as “lateral volts”). In the exploration and mining process to pay attention to the study of the side of the volcano. Only by investigating the sideways volcanoes of the ore body can we lay out exploration and mining projects reasonably, find ore bodies more quickly and economically, submit reserves and rationally mine.
