A system and method for employing a number of producer modules to produce and deliver recommendations to a requester. Each of the recommendations having associated therewith a confidence level. Each of the producer modules having associated therewith a weighting value. The confidence levels in each of the recommendations produced by the producers being modified based on weighting value associated with the producer that produced the produced recommendation. The weighing values associated with each of the producer modules being modified based on information from the requester related to the recommendations delivered to the requester.

A control system for a hydraulic percussion rock drill and feed mechanism including a single constant power hydraulic pump for supplying pressure fluid to operate the feed mechanism, drill stem rotation motor, and the percussion hammer. The drill feed, rotation and percussion functions are controlled by individual manually actuated pressure compensated valves. Fluid pressure to the feed mechanism is controllable at one of two selectable pressures and is automatically reduced if fluid pressure to the drill stem rotation motor exceeds a predetermined limit. The drill percussion blow intensity and frequency is controlled by a mechanism responsive to a fluid pressure signal which is automatically operated to provide for a high blow frequency and low blow intensity operating mode when the drill is retracted away from the workface. The constant power hydraulic pump is provided with a control which will adjust the pump output to a partial displacement setting when the drill is being retracted away from the workface. Alternatively, the pump control may be set to full displacement with a power limit and the drill percussion mechanism fluid supply may be automatically throttled when the drill is being retracted away from the workface.

In a pivotally mounted rock drill boom and feed bar apparatus, the pivots of the boom and the feed bar positioner include angle sensors comprising cam actuated fluid pressure regulating valves. The pressure regulating valves are disposed in a control circuit which includes a pilot pressure fluid actuated control valve which senses an unbalanced pressure signal generated by the sensor connected to the boom pivot in response to movement of the boom about said pivot. The control valve responds to the unbalanced pressure condition by valving fluid to the feed bar positioner actuator to maintain the feed bar in a predetermined directional attitude. The angle sensor mounted on the boom pivot may be adjusted independent of movement of the boom to cause a change in the directional attitude of the feed bar as desired.

A mobile rock drill unit (10) is disclosed which automatically adds and removes drill string sections (26) from the drill string (24) of the drill unit. The drill unit includes a conventional drill motor (20) and a centralizer (40). A cylindrical storage rack (34) is both rotatably and pivotally mounted to the mast (14) of the drill unit and has upper and lower rack members (62,64) with aligned fingers (116,118,176,178) to define a number of drill string section storage positions to store drill string sections therebetween. A roller clamp assembly (36) is provided which clamps the coupling (28). The coupling is clamped between rotatably mounted driven and idler rollers (296,322) and the axis of rotation of each of the rollers is canted relative to the drill string axis so that rotation of the driven rollers in a first direction will rotate the coupling and move it downwardly at a rate synchronized with the threads interconnecting the coupling and adjacent drill string section. A control system (38) is provided which automates the task of adding and removing drill string sections from the drill string.

A pilot pressure fluid operated spool type power fluid distributing valve for operating a hydraulically powered reciprocating piston pump includes a spool closure member with opposed unequal diameter bores formed in the spool ends. Pilot actuator pistons project into the bores and include pilot pressure fluid passages opening into the bores from sources of pilot control fluid. The bore of smaller diameter includes an enlarged annular chamber which may be closed by a cooperating ridge on the associated piston and a reentrant edge of the bore so that the closure member may be biased in one position if already in that position until a predetermined pilot fluid pressure is present in the opposite bore.

A flexible diaphragm for a hydraulic fluid accumulator is provided with a plurality of concentric circular ridges for engagement with the wall surface of the accumulator housing between concentric circular rows of fluid discharge openings formed in the housing. The ridges maintain the diaphragm in spaced relation to the discharge openings to prevent extrusion of the diaphragm into the discharge openings.

A rotary actuator is pivotally mounted on the end of a drill boom and supports a rock drill feed bar for rotation about a longitudinal axis of the actuator. The rotary actuator includes a piston with a piston rod portion having external and internal helical splines engaged with cooperating splines on the actuator housing and a rotating shaft, respectively. The shaft is connected to the feed bar and is operable to rotate the feed bar in response to axial movement of the piston. The axis of rotation of the shaft may be coincident with the longitudinal axis of the drill boom. The drill boom is mounted on a rotary actuator for swinging movement about a vertical axis.

In a hydraulic percussion rock drill the operation of the working fluid distributing valve is controlled to effect a variation in percussive blow energy and blow frequency by varying the piston hammer stroke. Actuation of the distributing valve is controlled by a remote controlled hydraulically actuated pressure control valve interposed in a fluid passage which conducts hydraulic fluid from the hammer bore to actuate the distributing valve. Substantially infinite variation of hammer impact blow energy between high and low limits provides for selecting the maximum penetration rate of the drill for any type of rock conditions. The hydraulic rock drill is connected to a source of hydraulic fluid supplied to the drill at substantially constant fluid power by a variable displacement constant power hydraulic pump.
