摘　　要：为验证大间距结构理论模型、实验室研究的结论 ,梅山铁矿在现场按 15m× 2 0m大间距结构参数建立了试验矿块 ,通过现场工艺试验 ,全面掌握了大间距结构条件下采矿的基本规律 ,确定了适合于 15m× 2 0m大间距结构参数的凿岩爆破参数、采掘设备配套、三级矿量优化管理等 ,在试验矿块研究的基础上 ,进行了少量推广 ,为大规模应用打下了基础。To verify the theoretical model of wide spacing structure and the conclusions of the laboratory test, Meishan Iron Mine established a test ore block with a 15m×20m parameter of wide spacing structure on production site. Through on site technological test, the basic law of mining with wide spacing structure was fully grasped. Drilling and blasting parameters, complementation of mining and driving equipment and optimization management of third class ore reserve that were suitable for a 15m×20m parameter of wide spacing structure were determined. Based on the investigation on the test block, some expended application was made, laying a foundation for the large scale application.
