Abstract
This report summarizes the results from the first year of an anticipated multiphase program to develop improved coal mining equipment which utilizes the cavijet tm cavitating water jet method. This laboratory parametric study demonstrated the advantages of cavitating jets over noncavitating jets in cutting coal, by producing comparable slot depths at one-fifth of the operating pressure, at better than one-half of the specific energy. These results suggest that cavijet-augmented mining devices can be developed with compact, low-pressure pumps. Thus, cavijet should be capable of operating with safer, lighter support equipment, while providing all of the advantages (reduction of dust and sparks, and reduced damage to cutters) of conventional hydraulic mining methods.
