Feasibility Analysis of Continuous Dot Sampling Method Applied in Roadway Sampling of Makeng Iron Mine
At present,the sampling method of the underground roadway is the continuous spot sampling method,when the ore with hard and flat structure is encountered,the continuous spot sampling can not be carried out on the same horizontal line,there is the phenomenon of floating sampling,it is difficult to ensure the continuity of the spot sampling,there may be some individual samples are not representative of the situation.Based on the above reasons,the methods of slot sampling,continuous sampling and core sampling are studied,and the sample data of different sampling methods are collected,the deviation between continuous sampling and drilling full core sampling and slot sampling was verified,and the reason of deviation was analyzed.
