Pressure detection mechanism for mining engineering

Abstract

The invention discloses a pressure detection mechanism for mining engineering, and relates to the technical field of mining. The pressure detection mechanism for mining engineering comprises a base, wherein the left side of the base is fixedly connected with a side plate through a bolt; the base is movably connected with a rotary block through a revolving shaft; the top of the base is fixedly connected with a measuring plate; the bottom of the rotary block is movably connected with a stress rod through a revolving shaft; and the bottom end of the stress rod is movably connected with the measuring plate through a revolving shaft. According to the pressure detection mechanism for mining engineering, a limiting tube and the measuring plate are improved, and the rotary block, the stress rod, astress plate and a threaded rod are used cooperatively, so that the pressure on the pressure detection mechanism can be buffered well according to the stress situation; damage to the pressure detection mechanism due to discontinuous different pressures with relatively large difference values on the pressure detection mechanism is avoided; and meanwhile the pressure which changes constantly can bemonitored and recorded in real time.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a pressure detection mechanism for mining engineering. Background technique [0002] Before mining, it is sometimes necessary to blast the mine. The average unit consumption of explosives in mine blasting is relatively high (more than 0.4kg / t raw ore), but the control of bulk rate is still not ideal. The reason for the preliminary analysis is that the parameter setting of the blasting hole network is not enough. Reasonably, it is caused by insufficient utilization of the explosive energy. As the depth of the blast hole increases, this problem will become more prominent. Therefore, it is necessary to optimize the parameters of deep hole blasting from the perspective of fully utilizing the explosive energy. For buildings and residential buildings, blasting vibration can easily cause conflicts between workers and farmers. As the height of the stage increases, the amount of explosive ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a pressure detection mechanism for mining engineering, which solves the problem that in the prior art, it is difficult to buffer the pressure of the pressure detection mechanism according to the stress situation, and it is easy to appear The pressure detection mechanism is damaged because the pressure detection mechanism is intermittently subjected to different pressures with large changes. At the same time, the existing pressure detection mechanism can only detect instantaneous pressure, and cannot monitor and record the pressure that changes constantly.
