## Abstract

A drilling machine, including a drill and a boom, are used for drilling boreholes in the face of a mine. A sensor may scan the mine and create a virtual environment representing the mine based on that scan. The drilling machine may include a computer for moving the drill and the boom from a first position to a second position based at least partially on evaluation of the kinematic redundancy of the drill and boom. This may be used to avoid a collision in moving the drill and boom from the first position to the second position.

## Claims

### Claim 1

A system for use in drilling one or more boreholes in a face of a mine, the system comprising:
a drilling machine including
a drill for drilling the borehole;
a boom for manipulating a position of the drill; and
a plurality of actuators adapted to move the drill or the boom;
at least one sensor adapted to scan at least a portion of the mine for the creation of a topological image of the mine; and
a computer configured to automatically move the drill and boom from a first position to a second position according to an algorithm based on the topological image of the mine, wherein the algorithm comprises determining a kinematic redundancy of the plurality of actuators prior to moving the drill and boom.

### Claim 2 (depends on 1)

The system of claim 1, wherein the at least one sensor comprises a LiDAR unit.

### Claim 3 (depends on 1)

The system of claim 1, wherein the computer is adapted to move the drill in a 180 degree turn about a horizontal axis.

### Claim 4 (depends on 1)

The system of claim 1, wherein the computer is further configured for determining if a collision will occur prior to moving the drill or boom from the first position to the second position.

### Claim 5 (depends on 4)

The system of claim 4, wherein the topological image comprises a three dimensional point cloud of the mine, and the determining comprises analyzing a plurality of drilling vectors of points within the point cloud to evaluate whether any of said vectors will intersect.

### Claim 6 (depends on 1)

The system of claim 1, wherein, upon determining a lack of kinematic redundancy, the algorithm is further adapted to move the drill and boom to a third position with kinematic redundancy.

### Claim 7 (depends on 1)

The system of claim 1, wherein the algorithm further comprises an iterative loop comprising
evaluating a series of joint positions of the drilling machine between the first position and the second position;
initiating movement of the drill and boom according to the series of joint positions; and
determining if a collision is imminent;
wherein upon determination that a collision is not imminent, returning to the evaluating step and continuing movement of the drill and boom according to the series of joint positions until the second position has been reached; and
wherein upon determination that a collision is imminent, the algorithm further comprises the step of either waiting for an obstacle to be moved before returning to the evaluating step or initiating movement of the obstacle.

### Claim 8

A method for use in drilling a plurality of boreholes in a face of a mine passage using a drilling machine including at least one drill, at least one boom, and a plurality of actuators adapted to move the drill or the boom, the method comprising:
scanning an environment of the mine to create a virtual environment representing at least a portion of the mine and at least a portion of the drilling machine;
determining a kinematic redundancy of the plurality of actuators in moving the boom and drill from a first position to a second position;
upon determining a presence of kinematic redundancy for at least one of the actuators, automatically actuating the at least one actuator for moving the drill and boom from the first position toward the second position according to an algorithm based on the virtual environment.

### Claim 9 (depends on 8)

The method of claim 8, further comprising the step of, upon determining a presence of no kinematic redundancy, moving the drill and boom to a third position in which kinematic redundancy is present.

### Claim 10 (depends on 8)

The method of claim 8, further comprising continuously monitoring the virtual environment for a potential collision based upon a vector analysis of movement of the drilling machine in the virtual environment.

### Claim 11 (depends on 10)

The method of claim 10, wherein upon determination of a potential collision, the method further includes the step of determining if an obstacle may be moved to avoid the potential collision, and moving said object if determined to be movable.

### Claim 12 (depends on 8)

The method of claim 8, wherein movement of the boom and drill from the first position to the second position comprises rolling the boom and drill 180 degrees about a vertical axis.

### Claim 13 (depends on 8)

The method of claim 8, wherein the virtual environment comprises a point cloud image.
