Abstract
Description
[0001] The invention relates to the field of mining, namely to technologies for monitoring the state of mine workings, and can be used for visual monitoring of the state of extraction chambers, the stability of roof rocks and pillars during coal mining using a deep seam mining complex, which relates to unmanned technologies.
[0002] A remote monitoring system for mine operations (US Patent No. 9234426 "Mine Operation Monitoring System") is known. It includes the collection of map data, dynamic display of mine equipment in real time, and the collection of equipment status data using GPS and wireless communications. The system allows for tracking the location, status, and operating parameters of equipment in the mine, providing information through a user interface.
[0003] The disadvantages of the analogue are the lack of the ability to visually monitor the condition of the extraction chambers, the stability of the roof rocks and the integrity of the inter-chamber pillars in conditions of complete darkness, limited adaptation to narrow and hard-to-reach sections of mine workings, the inability of the system to overcome local roof disturbances or rock falls, which lead to long downtimes, high capital costs for equipment extraction and an increase in the cost of production, dependence on stationary equipment for data collection, which reduces the mobility of the system.
[0004] The device closest in technical essence and the achieved result, adopted as a prototype of the present invention, was chosen (Bulletin of the Kuzbass State Technical University. 2019. No. 6, pp. 56-63, D.N. Dyagterev, A.I. Bykadorov, A.A. Renev, V.A. Volynkin "Video monitoring of the state of chambers and pillars during the development of reserves using the technology of deep seam development") for monitoring based on a self-propelled radio-controlled model on an all-wheel drive chassis with solid axles and four swivel wheels, with the installation of additional equipment in the form of front and rear cameras and backlighting, including remote control of the device with a remote control, transmission of a video signal to a video helmet, recording of files on the front camera and ensuring visibility in conditions of complete darkness. The device was developed for visual monitoring of the state of extraction chambers during their execution.
[0005] The prototype's shortcomings include its small size, which prevents it from overcoming localized areas of delamination of the protective coal pack or the squeezing of interchamber pillars, making further inspection of the mining chamber impossible. The installed remote antenna, when driving at an angle or over obstacles such as cave-ins or delaminations, can cause the self-propelled radio-controlled model to swing and overturn, leading to its loss and the impossibility of further inspection in an unmanned environment. There is also no protection for the equipment from possible delamination of roof rock.
[0006] The technical result of the claimed invention is to reduce emergency downtime, minimize equipment jamming and reduce the costs of its extraction.
[0007] The said technical result of the claimed invention is achieved in that the device for video monitoring and remote control of the parameters of deep seam development technology in areas of increased rock pressure includes a self-propelled radio-controlled model made on an all-wheel drive chassis with independent suspension, wherein the self-propelled radio-controlled model is protected from above by a durable protective cover, and on the sides - by a protective housing designed to prevent damage to the equipment in the event of possible peeling of roof rocks, while a reinforcing beam is provided in the body of the self-propelled radio-controlled model, and the front and rear wheels are equipped with independent shock absorbers, and the chassis is made with a large stroke of independent suspension and a low center of gravity, and in the front part of the self-propelled radio-controlled model a front-view camera with increased light sensitivity is located,mounted on a rotating platform to enable shooting in the vertical and horizontal planes, as well as two LEDs that provide directional illumination of the survey area, and on the upper part of the protective cover of the self-propelled radio-controlled model, additional lighting is installed in the form of a lensed LED module for operation in conditions of complete darkness, while in the rear part of the body of the self-propelled radio-controlled model, a rear-view camera is installed, designed to monitor the space when the device is moving backwards and when maneuvering. , while the electronics unit and antenna are located inside the protective housing to prevent damage, and the device is configured to transmit a video signal from the front and rear camera to the operator's video helmet at a frequency of 5.8 GHz, while in order to increase the range and stability of the signal, the device additionally includes a video signal amplifier connected to the front and rear view camera,wherein the device is designed with the possibility of being controlled using a control panel with two joysticks, where the left joystick is responsible for the movement of the self-propelled radio-controlled model, the right joystick is responsible for turning the front camera, and the toggle switch is for switching between the front and rear cameras.
[0008] The claimed invention is explained by drawings, where Fig. 1 shows a general view of a self-propelled radio-controlled model, Fig. 2 schematically shows a side view of a self-propelled radio-controlled model, Fig. 3 schematically shows a front view of a self-propelled radio-controlled model, Fig. 4 schematically shows a rear view of a self-propelled radio-controlled model, Fig. 5 shows a video helmet, a control panel and a video signal amplifier, Fig. 6 shows an image from a camera of a self-propelled radio-controlled model with information about the battery charge, time and tilt angle of the device.
[0009] This device for video monitoring and remote control of deep seam mining technology parameters in high-pressure zones includes a self-propelled, radio-controlled model mounted on an all-wheel-drive chassis with independent suspension, providing greater suspension travel and reducing machine roll when driving over uneven surfaces. The model is protected on top by a robust protective cover 1, and on the sides by a protective housing 2, designed to prevent damage to the equipment in the event of possible roof rock delamination. To increase structural rigidity and resistance to deformation, a reinforcing beam 3 is provided in the housing. The front 4 and rear 5 wheels are equipped with independent shock absorbers 6, ensuring a smooth ride and the ability to overcome localized unevenness and obstacles. For easy transportation outside the working area, a carrying handle 7 is installed on the housing.The front of the device houses a high-sensitivity front-view camera 8, mounted on a rotating platform for vertical and horizontal imaging, as well as two LEDs 9 providing targeted illumination of the survey area. A lensed LED module 10 provides additional, high-power illumination on the top of the protective cover 1 for operation in complete darkness. A rear-view camera 11, also highly sensitive, is mounted at the rear of the housing to monitor the surrounding area when the device is reversing and maneuvering. All electronics, including the antenna, are housed within the protective housing 2 to prevent damage and ensure stable communication. The video signal is transmitted to the operator's video helmet 12 via a 1.2 GHz frequency; a video signal amplifier 13 is additionally used to increase the range and stability of the signal.The device is controlled using a control panel 14 with two joysticks: the left joystick 15 controls the model's movement, the right joystick 16 rotates the front camera, and a toggle switch 17 switches between the front 8 and rear 11 cameras. The operator's video helmet 12 displays the image of the selected camera and, when using the front camera 8, additionally displays information about the battery charge, time, and tilt angle of the device. A measuring tape, attached to the tape loop 18 on the model's body, is used for emergency retrieval of the device and simultaneous distance monitoring.
[0010] The device for video monitoring and remote control of the parameters of deep seam development technology in areas of high rock pressure operates as follows.
[0011] This technology is unmanned, so entry into the excavation chamber is prohibited. Approaching the side of the excavation chamber is permitted at a distance of no closer than 6-10 meters, up to the safety shaft. From a safe distance, the operator turns on the self-propelled radio-controlled model and digital image recording. The self-propelled radio-controlled model is turned on using a button mounted on it. The control panel and video helmet are also activated using a button. The left joystick on the control panel controls the self-propelled radio-controlled model left, right, forward, and backward; the right joystick controls the front camera vertically and horizontally. The control panel features a toggle switch for switching between the front and rear cameras. The video helmet displays information about the selected camera. When selecting the front camera image, the battery charge, time, and tilt angle of the self-propelled radio-controlled model are displayed. When selecting the rear camera, this information is not displayed.Digital recording on the self-propelled radio-controlled model is performed only by the front camera, with backup analog recording made on the video helmet from the camera activated by the operator. The operator, using the control panel, enters the excavation chamber of the self-propelled radio-controlled model, which uses the camera to record any deformation processes. For detailed observation of the process, the camera rotates both vertically and horizontally. An additional light mounted on the top of the protective cover improves visibility in the surveyed area, while two LEDs mounted on the same platform as the camera provide focused illumination of the surveyed area. The operator's assistant, using a measuring tape used to pull the self-propelled radio-controlled model out of the way in the event of a rollover, reports the distance at which the deformation processes are occurring.After inspecting the mining chamber, the self-propelled radio-controlled model is driven using the rear camera to prevent the measuring tape from wrapping around the wheels and to facilitate maneuvering in difficult conditions. Based on the inspection results, the operator issues recommendations, or in difficult situations, a collective decision is made regarding the feasibility or impossibility of further safe modification of the mining chamber or recommendations for changing the mining parameters.
[0012] A device for video monitoring and remote control of the parameters of deep seam development technology in areas of increased rock pressure makes it possible to quickly assess the manifestation of rock pressure and select the criteria for optimal safety factors for these conditions, an increase in which leads to a decrease in the reserve recovery factor, and a decrease in which leads to emergency situations.
