Abstract

The specification describes a mining machine, in particular slot drilling machine for mining of minerals, especially ores of non-ferrous metals from narrow layers of reefs in hard rock, comprising at least one drilling head pivotable about a vertical pivoting axis for arcuate drilling of a slot cavity and a carrier comprising a front part and a rear part joined by thrust cylinders and hydraulic props supportable against the upper and lower slot cavity walls, characterized in the drilling head having at least one oscillation disc segment armed with at least two or preferrably more drilling tools and provided with at least one operation cylinder engaging eccentrically to the disc segment and this oscillation disc segment being supported oscillatingly in horizontal position about the vertical pivoting axis in the front part of the carrier.

Claims14

Dependent claims

A mining machine having a drilling head and a carrier, means pivotally mounting said head to the forward end of said carrier;

fluid operated means for arcuately reciprocating said drilling head about said pivot means;
said carrier having a first portion and a second portion, said portions being laterally pivotable with respect to each other about a veratical axis which is capable of limited travel both lengthwise and laterally of said machine;
a pair of laterally spaced hydraulic props mounted on one of said portions, one of said props being on each side of the longitudinal centerline of said machine, each of said props having extensible legs extending both above and below said carrier to provide floor and roof engagement;
at least one hydraulic prop mounted on the second of said portions and having extensible legs extending both above and below said carrier to provide floor and roof engagement;
a pair of extensible and retractable cylinders interconnecting said first and second portions, said cylinders being independently operable to pivot said portions with respect to each other and about one of said props by extension or retraction of said cylinders to enable said machine to execute a turn of 90.degree. substantially about its midpoint.

A mining machine for mining ores of non-ferrous metals from narrow reefs in hard rock, said machine having a drilling head and a carrier;

said carrier having a front portion and a rear portion, means pivotally mounting said head to said front portion;
hydraulic means for arcuately reciprocating said drilling head about said pivot means;
a pair of laterally spaced independently operable, fluid operated extensible and retractable cylinders interconnecting said front and rear portions and providing the only hinge connection between said portions;
a pair of fluid operated props on said front portion, each of said props having extensible and retractable legs projecting both above and below said front portion to provide floor and roof engagement;
said leg means being laterally spaced, one on each side of the longitudinal centerline of said machine;
at least one fluid operated prop on said rear portion offset laterally to one side of said longitudinal centerline, said portions with respect to each other being pivotal in incremental steps at least 90.degree. to either side about one of said props by selective extension and retraction of said cylinders and of said props whereby said machine may be made to execute a turn of 90.degree. about its approximate midpoint.
