Abstract
Abstract In the analysis of rock ahead of a working face a probe is pushed along a borehole formed in any desired direction in the rock and data produced by the probe is logged for later analysis, or for in-situ analysis. The probe may produce multiple logs. The data logged includes lithological information on the rock and the angular direction of the borehole. The presence of fluids, such as noxious gases, in the borehole can simultaneously be detected.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
81 words
A method of mining analysis in an underground mine comprising the steps of: forming a plurality of boreholes in predetermined directions in rock ahead of a rock face in said underground mine, at least one of said bore holes being at an angle to the others; for each borehole, locating a probe in the borehole; causing the probe to move along the borehole; and logging data which is obtained from the probe and which relates to the rock, in a recorder.
Claim 2
Independent Claim
81 words
A method of mining analysis in an underground mine comprising the steps of: forming a plurality of boreholes in predetermined directions in rock ahead of a rock face in said underground mine, at least one of said bore holes being at an angle to the others; for each borehole, locating a probe in the borehole; causing the probe to move along the borehole; and logging data which is obtained from the probe and which relates to the rock, in a recorder.
Claim 3
Dependent Claim
24 words
A method according to claim 1 which includes the step of processing and utilizing the data for optimum mining of ore in the rock.
Claim 4
Dependent Claim
25 words
A method according to claim 1 in which the data obtained from the probe is transmitted by means of a radio signal to the recorder.
Claim 5
Dependent Claim
21 words
A method according to claim 1 in which the logged data relates to the rock in which each borehole is formed.
Claim 6
Dependent Claim
24 words
A method according to claim 4 in which the logged data relates to the position, dimensions and grade of ore bodies in the rock.
Claim 7
Dependent Claim
17 words
A method according to claim 4 in which the logged data relates to discontinuities in the rock.
Claim 8
Dependent Claim
19 words
A method according to claim 1 wherein the probe provides data on a plurality of characteristics of the rock.
