Abstract
A continuous mining method includes operating a vibratory milling machine having a milling head, a base, and a milling tool to oscillate the milling head in a substantially linear reciprocating fashion relative to the base to move the milling tool along a milling axis; and advancing the vibratory milling machine in a work piece in a cutting direction and wherein milling axis is oriented at an attack angle relative to the cutting direction, the attack angle being between about 0 and about 40 degrees.

A continuous mining method, comprising:
- operating a vibratory milling machine having a base, a milling head positioned within a recess of the base, and a milling tool to oscillate the milling head in a linear reciprocating fashion relative to the base to move the milling tool along a milling axis;
- advancing the vibratory milling machine in a work piece in a cutting direction, wherein the milling axis is oriented at an attack angle relative to the cutting direction, the attack angle being between about 0 and about 40 degrees;
- and
- adjusting the angle of attack.
In a vibratory milling machine having a milling tool carried on a vibratory housing, the method of milling comprising:
- moving the milling tool in a substantially linear reciprocating manner along a milling axis by rotating at least two eccentrically weighted rotors within the housing to create vibratory forces, wherein the housing is resiliently secured to a supporting base;
- confining the housing to move in a substantially linear direction along a pair of channels of the supporting base;
- and
- advancing the vibratory milling machine in a cutting direction while moving the milling tool in a linear reciprocating manner along the milling axis in which the milling axis is disposed at an attack angle relative to the cutting direction, the attack angle being between about 0 degrees and about 40 degrees.
