Problems solved by technology

Some mines in foreign countries still use ultrasonic detection, infrared radiation detection and other means when "knocking for help and asking the top". However, due to technical and economic constraints in mines in my country, there are obviously problems with incomplete pumice detection and the safety of inspectors during detection. disadvantages such as threats

Embodiment 1

[0034] like figure 1 As shown, a pumice intelligent detection device includes an impact device, a data monitoring device and a signal processing terminal 7. The impact device includes an impact head 1, a cylinder 2, a valve 3 and a spring 4, etc. The data monitoring device includes monitoring and sending the top pumice stone receiving The shock sensor 5 for shock vibration data, the audio sensor 6 for the audio data of the impacted pumice stone on the roof; the signal processing terminal 7 includes a signal preprocessing system, a judgment system and a display system.

[0035] Through the data monitoring device, the vibration data of the impact of the pumice on the roof and the audio data of the impact of the pumice on the roof are monitored and sent. The signal preprocessing system, after receiving the vibration data of the impacted roof pumice stone and the audio data of the impacted roof pumice stone, filters the signal data and brings the data into the first functional rel...

Embodiment 2

[0041] On the basis of the above-mentioned Embodiment 1, the present invention also provides an intelligent detection method for pumice stones, the process of which is as follows figure 2 shown, including the following steps:

[0042] Step 1: constructing the first functional relationship between the vibration data and audio data of the impacted roof pumice and the hanging state of the roof pumice, and the ratio of the impacted audio amplitude to the vibration amplitude of the roof pumice to further determine the second functional relationship of the hanging state of the roof pumice, And the third function relationship of whether the hanging state of the pumice on the roof reaches the drop warning value;

[0043] Step 2: monitor the vibration data and audio data of the impacted roof pumice through the data monitoring device, and obtain the data of the basic hanging state of the roof pumice according to the first functional relationship;

[0044] Among them, the monitoring of...

Abstract

The invention discloses a pumice intelligent detecting device and method, and belongs to the technical field of roof pumice prediction. The intelligent detecting device comprises an impact device, a data monitoring device and a signal processing terminal. The impact device comprises an impact head, a cylinder, a valve and a spring. The data monitoring device comprises a vibration sensor for monitoring and transmitting impact vibration data of roof pumice and an audio sensor for monitoring and transmitting impact audio data of the roof pumice. The signal processing terminal comprises a signal preprocessing system, a judging system and a display system. The detecting device can detect the overhanging state of the roof pumice with high efficiency, accuracy and intelligence, reduces the dangerof 'tapping' and improves the work efficiency.

Description

technical field [0001] The invention relates to the technical field of roof pumice prediction, and more particularly, to an intelligent detection device and method for pumice. Background technique [0002] After the ore is mined, the overlying rock layer loses its support, and the original stress balance state before it is not mined is destroyed. Due to the action of gravity, the rock mass must have a tendency to fall, and the complex geological structure and the vibration of mining, excavation and blasting will increase the hidden danger of roof collapse. [0003] Improper handling of pumice stones, unskilled removal techniques, poor inspection, negligence or even no inspection are one of the casualties caused by roof fall. "Knock on the top and ask the top" is a flexible and effective turquoise detection method, which is the main method currently used at home and abroad. However, there are certain limitations when crowbar inspection and processing of turquoise. Some for...
