    摘要： Hard rock trenching apparatus comprised of a pair of spaced apart diamond toothed cutting blades mounted for rotation in combination with a hydraulically operated breakout tool having a chisel face supported behind the cutting blades in a plane located intervening within the spacing between the cutting blades. The tool is continuously operable for removing the center core remaining between the blades while an adjustable linkage enables positioning the chisel of the tool at or above the cutting plane of the blades.

    摘要： A method of controlling a longwall mining system, the longwall mining system including a longwall shearer, a conveyor, and a plurality of roof supports, such that the method includes creating, by a controller, a load profile of the conveyor representing a distribution of mineral along a length of the conveyor, calculating, by the controller, a desired change in the load profile based on the load profile of the conveyor, and controlling, by the controller, the longwall mining system to adjust the distribution of mineral on the conveyor based on the desired change in load profile.

    摘要： A rotary trench cutting or rock milling saw unit is supported on a head for movement about two mutually perpendicular axes. The head is adapted for pivotal mounting on a backhoe boom or similar positioning structure. Rotary rock cutting wheels are driven by a hydraulic motor and a support vehicle for the saw unit includes a hydrostatic drive system with a variable displacement hydraulic pump driving variable displacement track drive motors which may be set in a slow speed operating mode for trench cutting operations or a high speed mode for tramming between work sites. A constant rate of power input to the saw unit is maintained by sensing saw drive motor supply pressure and adjusting track drive motor supply pump displacement to maintain a constant feed or rock cutting rate. The apparatus includes hydraulically operated actuators for rotating the saw unit and its support boom about a vertical axis with respect to the apparatus undercarriage, elevating the boom with respect to the undercarriage, and moving the saw unit about three mutually perpendicular axes with respect to the support boom. Each of the actuators includes a control valve which may be selectively positioned to operate the actuators in reverse directions, lock the actuators in a predetermined position, or permit the actuators to oscillate or rotate the saw unit with respect to the various positioning axes of rotation when the saw unit is confined in a trench.

    摘要： A mining machine includes a chassis, a cutting assembly coupled to the chassis, and a spray arm coupled to the chassis and positioned proximate the cutting assembly. The chassis includes a first end, a second end, and a chassis axis extending between the first end and the second end. The chassis is movable in a direction parallel to the chassis axis. The cutting assembly includes an arm and a rotatable cutting drum having a plurality of cutting elements. The spray arm includes a first portion, a second portion pivotably coupled to the first portion, and at least one spray nozzle for emitting a fluid spray in a region adjacent the cutting assembly. The first portion is coupled to the chassis and extends away from the chassis along a spray arm axis. The second portion is pivotable relative to the first portion about a wrist axis.

    摘要： A guide assembly for a longwall shearer. The shearer includes an arm having an arm end and a cutting drum rotatably coupled to the arm end. The cutting drum rotates about a drum axis and engages a mine wall, and the cutting drum has a rear extent arranged in a plane substantially perpendicular to the drum axis. The guide assembly includes a guide member coupled to the arm and operable to guide material won from the mine wall. The guide member has a guide surface extending in a direction non-parallel to the plane and non-parallel to the drum axis. The guide member guides material along the guide surface away from the cutting drum.
