Abstract

An apparatus, rock drilling rig, method and computer program for executing navigation for a rock drilling rig in a mine tunnel. The rock drilling rig is positioned at faces of rounds and is navigated before initiating drilling. The navigation is executed without a predetermined tunnel line. The realized tunnel line is formed by combining navigation data on several rounds. Length and direction of the round to be drilled next may be adjusted according to need.

First claim

The invention claimed is:

1. An apparatus comprising at least one data processing device for executing at least one navigation program in order to navigate a rock drilling rig in a mining tunnel, wherein the mining tunnel is advanced in several successive rounds and the navigation is executed for each round before initiating drilling by means of the rock drilling rig; and wherein the apparatus:
is provided with positioning data relating to determined position and direction of the rock drilling rig relative to a previously excavated round;
is configured to determine direction and length of each following new round in response to input data and is configured to take a selected direction and length into consideration in the navigation;
is configured to generate a tunnel line for the mining tunnel by combining the navigation results of each successive rounds one by one;
is configured to execute coordinate transformations between a machine coordinate system of the rock drilling rig and a mine coordinate system; and
is configured to present the produced mining tunnel line in the mine coordinate system, wherein the navigation is executed without a pre-determined mining tunnel line.

2. The apparatus as claimed in claim 1 , wherein the apparatus is provided with data specific to individual rounds; and the apparatus is configured to combine the round specific data with the produced mining tunnel line.

3. The apparatus as claimed in claim 1 , wherein the apparatus is configured to display the produced mining tunnel line with the realized drill holes and round specific data on a display device.

4. The apparatus as claimed in claim 1 , wherein the direction of the mining tunnel is determined during the navigation process of each round and the apparatus is configured to adjust the directions of the rounds on the basis of received manual control commands.

5. The apparatus as claimed in claim 1 , wherein the apparatus is configured to present on a display device graphical input elements allowing change of horizontal direction and change of vertical direction before finalizing navigation of the rock drilling for the following new round to be drilled.

6. The apparatus as claimed in claim 1 , wherein the apparatus is provided with input data on a modified length of the round, whereby the apparatus is configured to adjust length of a drilling pattern for the next round in response to the input data of the modified length.

7. The apparatus as claimed in claim 1 , wherein the apparatus is located onboard a rock drilling rig, whereby the mining tunnel line is generated at the drilling site during the operation of the rock drilling rig, and the apparatus further comprises a data communication device for communicating the generated mining tunnel line at intervals from the drilling site to at least one external electronic device.

8. The apparatus as claimed in claim 1 , wherein the apparatus is configured to attach pre-designed drilling patterns to each round during the navigation, wherein the drilling patterns include data on drill holes to be drilled, and wherein the apparatus is configured to execute coordinate transformations between coordinate systems of the rock drilling rig, the drilling pattern and the mine.

9. The apparatus as claimed in claim 1 , wherein the apparatus is provided with scanning data of rock surfaces surrounding the rock drilling rig during the navigation procedure, whereby the scanning data includes data on realized shapes and dimensions of each previous rounds, and wherein the apparatus is configured to combine the scanning data with the generated mining tunnel line.

10. A rock drilling rig comprising:
a movable carrier; and
at least one drilling boom connected movably to the carrier and equipped with a drilling unit, wherein the rock drilling rig is provided with an apparatus in accordance with claim 1 .

11. A method of navigating a rock drilling rig in a mining tunnel, which mining tunnel is created by utilizing drilling and blasting methods, wherein rock material is removed in several successive rounds, the method comprising:
positioning the rock drilling rig at faces of the successive rounds;
executing the navigation for each round before initiating drilling by means of the rock drilling rig;
attaching in the navigation a coordinate system of the rock drilling rig to a mine coordinate system; and
determining a mining tunnel line for the realized mining tunnel by combining navigation data of the several successive realized rounds, whereby the navigation is executed without a pre-determined mining tunnel line.

12. The method as claimed in claim 11 , further comprising deciding a direction of each new round only after the navigation.

13. The method as claimed in claim 11 , further comprising deciding a length of each new round only after the navigation.

14. The method as claimed in claim 11 , further comprising
generating sensing data during operation in the mining tunnel; and
linking the generated sensing data to the navigation data and thereby producing round specific sensing data.

15. The method as claimed in claim 14 , further comprising
analyzing the realized mining tunnel line and the round specific data; and
presenting at least one point of interest on a display device in response to the executed analysis.

16. A computer program product for executing mining navigation for a rock drilling rig in a mine, wherein the computer program product comprises program code means configured to execute the steps and procedures of claim 11 when being run on a computer or a data processing device.
