摘　　要：本文以务川大竹园铝土矿床为例,用100×100 m和200×100 m钻探工程网度分别与200×200 m钻探工程网度进行对比,对其矿体厚度、矿体形态、主要化学成份含量及资源量变化进行分析对比,100×100 m或200×100 m工程网度都能更好地控制矿体形态、厚度、空间位置和矿石质量。勘探网度放稀圈定矿体更为合理,达到了事半功倍的效果。因此,对务正道地区沉积型的铝土矿床勘探,不能机械地套用勘探工程网度,应根据规范合理加密工程控制,从而满足矿山开采设计和生产的要求。Dazhuyuan bauxite deposit is taken as the example, the thickness, shape, major chemical content and resources of different exploratory grid （100×100 m, 200×200 m） are compared, the exploratory grid can control the shape, thickness, spatial position and ore better. Orebody determination by exploratory grid is more reasonable and effective. Therefore, the bauxite exploration in Wuzhengdao area not only use exploratory grid but also regulates the reasonable encryption engineering control, so the mine design and the production are satisfied.
