Abstract

An arrangement and method of utilizing rock drilling information in a mine whereby drill holes are drilled in a surrounding rock material by a first mining vehicle. During drilling measuring data is produced and is inputted to a monitoring device for analyzing procedures. The monitoring device produces rock condition data of the rock material being drilled. The produced rock condition data is then implemented in a second mining vehicle.

First claim

The invention claimed is:

1. An arrangement for utilizing rock drilling information, wherein the arrangement comprises:
at least one first mining vehicle having at least one rock drilling machine for drilling drill holes in a surrounding rock material;
at least one measuring device disposed in the first mining vehicle arranged to produce measuring data of the rock drilling;
at least one monitoring device for monitoring the rock drilling based on measuring data received from the at least one measuring device, the at least one monitoring device being located in the first mining vehicle and including at least one data processing device for analyzing the received measuring data of the rock drilling, the at least one monitoring device in the first mining vehicle being configured to produce, in real-time, at least one rock condition data of the rock material being affected by the rock drilling; and
at least one data transfer connection for transmitting the produced rock condition data from the monitoring device in the first mining vehicle to at least one control unit of at least one second mining vehicle, wherein the rock condition data produced at the first mining vehicle is configured to influence operation of the at least one second mining vehicle.

2. The arrangement as claimed in claim 1 , wherein the second mining vehicle includes at least one mine work device for affecting rock material, the operation of the mine work device of the second mining vehicle being arranged to be influenced according to the received rock condition data.

3. The arrangement as claimed in claim 1 , wherein the rock condition data includes data on joints and faults in the surrounding rock material.

4. The arrangement as claimed in claim 1 , wherein the rock condition data includes data on cracks in the surrounding rock material.

5. The arrangement as claimed in claim 1 , wherein the rock condition data includes data on fragmentation of the surrounding rock material.

6. The arrangement as claimed in claim 1 , wherein the rock condition data includes data on cavities of the surrounding rock material.

7. The arrangement as claimed in claim 2 , wherein the at least one mine work device of the second mining vehicle is a rock bolting device, which includes a rock drilling machine for drilling reinforcing holes in the surrounding rock material.

8. The arrangement as claimed in claim 2 , wherein the at least one mine work device of the second mining vehicle is a rock drilling machine for drilling production drill holes in the surrounding rock material for detaching ore by a drilling and blasting method.

9. The arrangement as claimed in claim 2 , wherein the at least one mine work device of the second mining vehicle is a reinforcing material feed device for feeding reinforcing fluid material into the drill holes drilled by the first mining vehicle.

10. The arrangement as claimed in claim 1 , wherein the at least one first mining vehicle is a face drilling rig, the face drilling rig including drilling means for drilling blasting holes in a face of an underground rock space, the drilling means including at least one drilling boom and a drilling unit at a distal end of the drilling boom, the monitoring device of the first mining vehicle being configured to produce at least one rock condition data of the rock material being drilled by the face drilling rig, and the at least one second mining vehicle being arranged to execute mining work affecting the surrounding rock material of the underground rock space produced by the face drilling rig.

11. The arrangement as claimed in claim 10 , wherein the monitoring device in the first mining vehicle is configured to estimate position and direction of defects in the surrounding rock material of the underground rock space based on the produced rock condition data.

12. The arrangement as claimed in claim 10 , wherein the at least one second mining vehicle includes at least one rock bolting device for arranging several reinforcing bolts in a bolting pattern, the rock bolting device including a rock drilling machine for drilling several reinforcing holes in the surrounding rock material of the underground rock space for forming a reinforcing drill hole pattern, and a mounting device for inserting the reinforcing bolts to the drilled reinforcing holes of the reinforcing drill hole pattern, the monitoring device in the first vehicle being configured to observe deviations in rock material surrounding the underground rock space, and the second mining vehicle being configured to direct the reinforcing holes according to the observed defects.

13. The arrangement as claimed in claim 10 , wherein the at least one second mining vehicle includes at least one rock bolting device for arranging several reinforcing bolts in a bolting pattern, the rock bolting device including a rock drilling machine for drilling several reinforcing holes to the surrounding rock material of the underground rock space for forming a reinforcing drill hole pattern, and a mounting device for inserting the reinforcing bolts to the drilled reinforcing holes of the reinforcing drill hole pattern, the monitoring device in the first mining vehicle being configured to observe deviations in rock material surrounding the underground rock space, and the second mining vehicle being configured to determine distance of successive reinforcing drill holes according to the observed defects.

14. The arrangement as claimed in claim 1 , wherein the at least one second mining vehicle includes at least one rock bolting device and at least one control unit for controlling the operation of the rock bolting device, the second mining vehicle including at least one display device, and the control unit being configured to indicate the detected defects on the display device for an operator of the second mining vehicle.

15. The arrangement as claimed in claim 14 , wherein the control unit is further arranged to show automatically a proposal for drilling the reinforcing drill holes.

16. A method of utilizing rock drilling information, the method comprising:
drilling drill holes in a rock material by at least one first mining vehicle provided with at least one drilling machine;
producing measuring data during the drilling;
gathering the produced measuring data;
inputting the measuring data to at least one monitoring device located in the at least one first mining vehicle;
monitoring the drilling on the basis of the measuring data in the monitoring device;
producing in the monitoring device located in the at least one first vehicle, in real-time, at least one rock condition data of the rock material being drilled;
transmitting the produced rock condition data from the at least one first vehicle to at least one second mining vehicle; and
controlling the operation of the at least one second mining vehicle based on the rock condition data received from the at least one first vehicle.
