Problems solved by technology

[0002] With the increase of coal mine mining depth, the problem of rock burst is becoming more and more serious, resulting in the impact damage of the surrounding rock of the roadway, the damage of the support, and the collapse of the roadway, which seriously threatens the safety of personnel and slows down the production progress.
The impact tendency is the inherent property of coal rock to generate rock burst. It is an index to measure the strength of coal rock impact. It can be measured through indoor experiments. The indoor pressure testing machine currently used is used to measure the standard coal rock that has been cut and ground from the underground. Similarly, due to the fragility of the coal and rock mass, it is difficult to take out the coal rock sample. Even if the coal rock sample is taken out, it is relatively hard and does not have the representativeness of the underground coal rock formation. In addition, the test process requires sampling, processing, testing and other steps, which is time-consuming and labor-intensive. higher cost

Abstract

The invention belongs to the technical field of mining, and particularly relates to a rock burst tendency testing gun and a testing method. The testing gun includes an impact energy supplying part andan intelligent monitoring part. The impact energy supplying part includes a gun grip, an electromagnetic trigger, a bore, a spring, a rotary dial plate, a gun barrel, a gun body, a bolt, and an impact head. The intelligent monitoring part includes an acceleration sensor, a display, a keyboard, a single chip microcomputer, a storage, a power supply and a WiFi module. The testing gun has advantagesof a small size, carrying convenience, simple operation and rapid measurement. Compared with traditional rock burst tendency tests, the testing gun and the testing method can save time and labor, reduce the cost, avoid a problem that a rock sample is difficult to prepare because a rock body is fragile, and avoid a problem that rock samples are harder than surrounding rock bodies so that the samples are not representative.
