It can be understood that, when adjusting the avoidance position and the anchor protection position of the first drilling mast assembly 33, the position of the first drilling mast assembly 33 can be adjusted cooperatively through the lifting assembly 31 and the working platform 32, for example, when the cutting drum 21 is lowered When there is a foreign object and the cutting arm cannot swing to the lowest position, the working platform 32 can be raised to a position suitable for the height of the cutting drum 21 through the lifting assembly 31, and then the working platform 32 can be extended forward and passed through the stable Assembly 34 presses against cutting device 2 .

During the excavation process, the bolter miner 100 can adopt two modes of operation, parallel operation and non-parallel operation, wherein the parallel operation is the operation mode of excavation and anchor protection at the same time. During operation, the first drilling frame assembly 33 needs to be withdrawn to Avoid position, at this moment, cutting device 2 can carry out cutting operation ahead, and the first drilling stand assembly 33 then can carry out anchor protection operation at the rear of cutting device 2. The method of parallel operation is suitable for the roadway roof with better conditions. At this time, there may be a certain empty roof distance between the head of the roadway and the anchor protection position.

The non-parallel operation means that excavation and anchoring are carried out alternately. When the non-parallel operation is performed, the cutting of the coal wall is first completed through the cutting drum 21, and then the cutting drum 21 can be swung to the bottom through the cutting arm, and then The first drill frame assembly 33 is moved above the cutting drum 21 through the lifting assembly 31 and the working platform 32, so that the anchor protection operation can be completed. The non-parallel operation method is suitable for roadway roofs with poor conditions. After a head-on advance is made, the roadway roof close to the head can be supported in time, which shortens the empty roof distance at the head and avoids the collapse of the roadway roof. Improve the safety of excavation work.

The drilling device 6 is arranged on the frame 1. The drilling device 6 includes a drilling machine 61 and a sensor. The sensor is electrically connected to the drilling machine 61. The drilling machine 61 is suitable for drilling the roadway floor and/or the roadway roof. The sensor is suitable for monitoring the drilling machine 61 when the drilling machine 61 is drilling. The set parameters and generate monitoring data signals.

Specifically, the drilling rig 61 can be a bolter rig 61, and the drilling rig 61 can carry out drilling operations such as drilling, drilling rock samples, etc., and the setting parameters of the drilling rig 61 can be the propulsive force of the drilling rig 61. At this time, the sensor can be a pressure sensor. When the drilling machine 61 drills holes on the roadway floor or the roadway roof, the sensor can monitor the reverse force of the formation on the drilling machine 61, which can be regarded as the interaction force with the required driving force of the drilling machine 61, thus , the monitoring of the propulsion force of the drilling rig 61 can be realized.

Because different strata have different lithologies, the propulsion force that the drilling rig 61 needs to apply when drilling is also different. For example, because the coal seam is soft, the propulsion force that the drilling rig 61 needs to apply when drilling the coal seam is relatively small. Due to the hard texture of the rock formation, the drilling rig 61 needs to exert a relatively large propulsion force when drilling the rock formation. Whether the drilling rig 61 is drilling is a rock formation or a coal seam can be judged by monitoring different propulsion forces.

It can be understood that, in some other embodiments, the setting parameters of the drilling rig 61 may also be some parameters that can reflect the nature of the formation, such as the working power of the drilling rig 61 and the pressure of the hydraulic system. At this time, the sensor is a sensor that can monitor the corresponding parameters .

The cutting device 2 and the sensor can both be electrically connected to the control device, and the control device is adapted to receive and analyze the monitoring data signal. During the process of the drilling rig 61 drilling the first thickness of the roadway floor, if the monitoring data signal is greater than the first threshold value, the control device It is suitable for reducing the minimum swing angle; in the process of the drilling rig 61 drilling the second thickness of the roadway roof, if the monitoring data signal is greater than the second threshold, the control device is suitable for reducing the maximum swing angle.

Specifically, the control device may be a PLC control system, and of course may also be other types of controllers or processors. The sensor can be electrically connected with the control device through wires, and in some other embodiments, the sensor can also transmit data signals with the control device through wireless transmission. The control device can be fixed on the inner side of the frame 1, so as to have a protective effect.

The monitoring data signal monitored by the sensor can be transmitted to the control device, and the control device can convert the received monitoring data signal into a numerical parameter, and then compare it with the preset first threshold or second threshold, and finally pass the comparison result Control the swing of the cutting arm. Wherein the first threshold is the numerical parameter corresponding to the propulsive force when breaking through the interface between the coal seam and the rock layer below the coal seam, and the second threshold is the numerical parameter corresponding to the propulsive force when breaking through the interface between the coal seam and the rock layer above the coal seam. The first threshold and the second threshold may take the same value or different values according to actual conditions.

It should be noted that the first thickness is the thickness of the bottom plate drilled by the drilling rig 61 when drilling the roadway floor, and the second thickness is the thickness of the roof drilled by the drilling rig 61 when drilling the roadway roof. The first thickness and the second thickness need to be selected according to needs and experience. For example, the first thickness can be the thickness of the remaining coal seam allowed by the bottom plate, and the second thickness can be the thickness of the remaining coal seam allowed by the roof.

For example, in the process of the drilling rig 61 drilling the first thickness of the floor of the roadway, the control device can receive the monitoring data signal in real time, and the control device will compare the monitoring data signal with the first threshold after receiving the monitoring data signal. When the numerical parameter corresponding to the monitoring data signal is greater than the first threshold, at this time, it can be judged that the cutting device 2 has cut to or adjacent to the rock layer below the coal seam, and the minimum swing angle β of the cutting arm is adjusted to a smaller value by the control device , the cutting drum 21 of the cutting device 2 can avoid subsequent cutting of the lower rock formation.

During the drilling operation of the drilling rig 61 on the roof of the roadway, the control device can receive the monitoring data signal in real time, and the control device will compare the monitoring data signal with the second threshold after receiving the monitoring data signal. When the monitoring data signal When the corresponding numerical parameter is greater than the second threshold value, at this time, it can be judged that the cutting device 2 has cut to or adjacent to the rock formation above the coal seam, and the highest swing angle α of the cutting arm is adjusted to a small value by the control device, cutting The cutting drum 21 of the device 2 can avoid subsequent cutting of the upper rock formation.

It should be noted that, as the bolter miner 100 advances, the drilling operation can be performed at every cycle footage, or can be performed at intervals of a set number of excavation cycle footage. The timing of the drilling operation can be selected according to the needs.

It can be understood that in the present disclosure, a monitor for whether the drilling device 6 is drilling the roof of the roadway or the floor of the roadway can be added. The monitor can be a position monitor, such as an infrared monitor, and the position monitor can monitor the position change of the drilling device 6 , so as to provide a basis for the control device to judge whether to drill the top plate or the bottom plate.

The bolter 100 of the embodiment of the present disclosure can realize parallel and non-parallel operation of excavation and anchor protection, and can select the corresponding excavation method for different roadway roof conditions, thereby improving the flexibility of the roadway excavation process It is beneficial to ensure the safety and efficiency of excavation.

Since the stabilizing component 34 is provided, the stabilizing component 34 can effectively support the roof during the anchoring operation, thereby ensuring the stability of the structure during the anchoring operation.

In addition, since the cutting direction of the cutting device 2 can be corrected in time by the drilling device 6 and the control device, the situation that the cutting device 2 cuts the roof and floor rock formations is avoided, so that the cutting device 2 can always cut in the coal seam. cutting work. Since the situation of cutting the roof and floor rock layers is avoided, the situation that a large amount of coal resources are left in the roof coal seam or the floor coal seam opposite to the offset direction due to the large deviation of the cutting direction is avoided, and the recovery rate is improved.

Since the bolter 100 works in the coal seam, it avoids the situation that the bolter 100 cuts the hard rock formation, thereby avoids the situation that the bolter 100 is easily damaged when cutting the rock formation, and ensures the stability of the tunneling operation It prolongs the service life of the equipment, reduces the amount of gangue mining, and realizes the green and efficient mining of coal seams.
