These problems can lead to: the ore loss rate is greatly increased; the drilling is too long and the explosives are not matched, so that the drilling cost and the explosive cost are increased; disasters, hidden dangers and the like caused by timely intervention are not provided after the drilling is carried out to the geological dangerous area. Secondly, it is difficult to establish a refined three-dimensional geological model. The dilution rate and the loss rate in the underground mining of the metal ore depend on a geological three-dimensional model, which are the service life of the mine and main technical and economic indexes, but are difficult to control and count in the mining process, mainly because the geological work of mineral resources is not developed enough, but under the current geological exploration process, the refined geological work, the construction of a transparent mine, a large amount of manpower and material resources are needed, and the development is difficult. (2) The geological coring off-line detection consumes long time.
In order to solve the problems, the invention provides a magnetic ore body occurrence state while drilling real-time detection device in an underground mining area, which combines a drilling trolley and related accessories, collects ore pulp obtained by flushing in a drilling process in real time by utilizing an inductance principle, immediately detects the content of magnetic minerals in the ore pulp by utilizing related instruments, judges the occurrence condition of an ore body in a rock stratum, and from the angles of different mechanical properties of the drilling rock mass, the ore body and the geological disaster risk area, a plurality of sensors and matched data acquisition and processing systems (ore body occurrence condition identification systems based on drilling parameters) are applied, and collecting mechanical parameters of rocks in the rock drilling process, feeding back a calculation result in time, and comparing the calculation result with the thickness of an ore body, the occurrence condition of gangue inclusion, the grade partition of the ore and the like judged by the drilling fluid magnetic substance content real-time monitoring device to further improve the accuracy and the reliability of the identification system.

(2) The content and occurrence state of the magnetic minerals are monitored and obtained on site in real time, and compared with sampling off-line detection, the on-site magnetic mineral content and occurrence state detection method saves working hours and greatly reduces time cost.
A more specific implementation is given below to further illustrate the above embodiments.
And the magnetic mineral detection device and the drilling monitoring system are synchronously started for measurement.
1. Magnetic mineral detection device
As shown in fig. 1 and 2, the magnetic mineral detection device comprises an ore pulp collection tray 4, a coil sensor, a data measurement processor 10, a fixed support 11 and the like, wherein a drill rod 3 of the drill jumbo penetrates through the ore pulp collection tray 4, a coil sensor connecting pipe and the coil sensor are uniformly and firmly supported by the fixed support 11, the middle part of the coil sensor is connected with the data measurement processor 10 through a connecting wire 9, and the instrument is reset to zero for processing and is ready for measurement.
The drilling jumbo drills upward blast holes, a flushing device for flushing drill cuttings is arranged at the drill bit 1, flushed ore pulp completely flows into an ore pulp collecting tray 4 at the bottom of a drill rod 3 along the drilled blast holes, the ore pulp passes through a coil sensor at a constant speed through a connecting pipe 5, and a measuring system starts to work and records in real time.
1) The working principle of the detection device is as follows:
when the ore slurry containing ferromagnetic minerals dynamically passes through the glass steel tube 8 of the coil sensor, only the magnetic dense medium causes the inductance value of the coil to change, and other components do not cause the inductance value to change. The inductance value is detected in real time, so that the aim of detecting the content value of the magnetic dense medium in real time can be fulfilled.
2) The detection principle is as follows:
as shown in formula (1), the inductance value of the coil sensor is only related to the length L, the number of turns N and the cross-sectional area S of the coil, and when the parameters are fixed, the inductance value L is only related to the magnetic permeability mu 0 And is linear with inductance value. The magnetic permeability is influenced by the content of the magnetic substances in the glass steel tube 8, and other substance components cannot cause the change of the value of the magnetic substances, so that the more the content of the magnetic substances is, the higher the magnetic permeability is, and the higher the inductance value is.
L＝μ 0 N 2 S/l (1)
When the suspension liquid flows through the glass steel tube 8 of the coil sensor, the content of the ferromagnetic magnetic dense medium influences the size of the inductance value L of the sensor, and the value is derived according to the Lenz law:
i represents the induced current, t represents the time, and as can be seen from the formula (1) and the formula (2), the sensor voltage V1 changes with the change of the content of the magnetic substance in the tube, and the higher the content, the higher the voltage. Therefore, the voltage value of the coil sensor reflects the change of the magnetic substance content in the glass steel tube 8.
3) Introduction of the working process of the detection device:
a. firstly, the single chip microcomputer is used for controlling and generating an excitation signal, the excitation signal is applied to the coil sensor, and induced electromotive force is generated at two ends of the coil sensor. In the measuring process, the internal resistance of the coil sensor changes along with the change of the temperature, and in order to prevent the temperature drift from influencing the measuring result, the sinusoidal current signal is selected as the excitation signal to avoid the internal resistance interference. In order to obtain a stable excitation signal, a stable and reliable square wave signal with the value of 100Hz is generated by utilizing a single chip microcomputer, then the signal is set in a filtering mode, and a sinusoidal voltage signal with corresponding frequency is obtained after the signal is set by an active filter circuit. The sinusoidal voltage excitation signal is converted into a sinusoidal current excitation signal through a voltage-current conversion circuit, and the amplitude value is about 20 mA.
b. And measuring the voltage value of the coil sensor and sending the measured voltage value to the singlechip. Through phasor voltage measurement circuit, voltage translation circuit, AD converting circuit, can measure sensor voltage V1 and internal resistance voltage V2, know by ferromagnetic mineral content measurement principle, just can obtain sensor inductance value through the phasor ratio of gathering sensor voltage V1 and internal resistance voltage V2 signal.
c. The inductance of the coil sensor is obtained through correlation calculation, and the content of the magnetic minerals can be correspondingly known according to the direct proportion relation between the inductance and the content of the ferromagnetic minerals, and is shown in a time-magnetic content relative value format. Due to synchronous working, the recorded time can correspond to the time recorded in the DPM type drilling monitoring system, and the drilling displacement can correspond to the content of the magnetic substances in the ore pulp through the time, so that the content value of the magnetic substances is accurately matched to a specific position in the ore body.

Due to the difference of mechanical properties, if step changes of the drilling rate and the drilling torque occur in the drilling process, or through a large amount of field test experience, the change threshold values of the drilling rate and the drilling torque of the iron ore body are determined, the situation that the drilling machine crosses the boundary between the ore body and the rock body or crosses the gangue inclusion in the ore body can be judged, and data measured by the laser displacement sensor 13, namely the specific height of the boundary between the ore body and the gangue inclusion in the drilled hole, is recorded.
