With the expansion of production and exploration to the outer periphery ， it is urgent to carry out research on the rationality of the layout of the exploration project to effectively control the exploration risk and provide technical support for the mine"s next prospecting. Through the study of the interval and network degree of the known ore body exploration project， and then the comparative analysis of the ore body data in different middle sections and different network degrees is conducted ， and the reference network degree in the next work of the mine is comprehensively obtained： the depth is greater than 300m ， the pre-inspection network degree is 200×100m， depth is 200～300m， survey network degree is 120×80m， depth is 100～200m， the detailed investigation network degree is 50×50m， depth is 0～100m， and the exploration network degree is 25×50m. 1下载后可任意编辑 Key words： survey engineering layout;rationality of survey network degree;contact zone deposit;old factory orefield;Gejiu tin mine 0 引言 随着老厂矿田井下无轨设备的推广应用，矿山开拓方式，系统建设，采矿方法等方面发生了变化。为了推动公司的快速进展，对矿产资...
