In response to the problems of large mining range, ore dilution rate, low mechanization degree, and high safety risksin the shallow hole shrinkage mining method for sharply inclined thin ore veins in China, taking the occurrence conditions of acertain metal mine as the engineering application

The numerical control processing technology is used to process the drilling tool, and the high-precision numerical control processing center is adopted, by matching the special wear-resistant coating cutter, the precision error of each process can be reduced by precise measurement, the production
