Abstract:

According to the mu tation orebody of Xinhui Gold mine,we exploit the orebody using subsection preparatory working,continous mining,caving orebody using upward sector medium-lengthhole continuous extrusion method, removaling ore using carry scraper,filling withclassification tailing of the comet, and get a good result.

Key words: Continuous mining, Tight blasting, Middle-lengh hole, Lower grade ore, Thick-big ore, Xinhui gold mine, Shandong Province
