Embodiment 1

[0042] A coal mine gas test monitoring device and method, see Figure 1 to Figure 12 , including the ventilation pipe that can be installed into the ventilation pipeline of the mine entrance, the monitoring mechanism 2 and the detection ball 12 are installed at both ends of the pull rope 1, and the circuit connection is set in the pull rope 1 to connect the monitoring mechanism 2 and the detection ball. 2 Including display screen, information storage terminal;

[0043] The center of the detection ball 12 is provided with a hollow hemispherical equipment mounting shell 3, the center of the mounting shell is the center of the Cartesian coordinate system, the two horizontal directions are the X and Y directions, and the axis in the vertical direction is Z. In the direction, the equipment mounting shell 3 is covered with an elliptical X-axis reset hub 4, the horizontal axis of the X-axis reset hub 4 coincides with the centerline of the equipment mounting shell 3 in the X direction...

Embodiment 2

[0058] The principle of this embodiment is the same as that of Embodiment 1. The specific difference is that, in this embodiment, dynamic detection may also be included. After step (2), the rolling mechanism is used to realize the remote control of the detection ball 12 to roll to the depth of the mine. close to reduce the influence of the air duct on the measurement results.

Abstract

The invention relates to a coal mine gas test monitoring device and method. The invention aims to solve the problem of limited working area and inaccurate monitoring of the gas concentration test monitoring device in the prior art. A monitoring mechanism and a detection ball are respectively installed at both ends of the stay rope, and a circuit connection line is arranged in the stay rope to connect the monitoring mechanism and the detection ball with a circuit. The monitoring mechanism includes a display screen and an information storage terminal; the detection ball includes a hollow The semi-spherical equipment installation shell, the Z-axis reset hub is set outside the equipment installation shell, the X-axis reset hub is set outside the Z-axis reset hub, and the outer spherical shell of the detection ball is set outside the X-axis reset hub. The air hole and the outer spherical shell are fitted with a clamp through a bearing-type connection mechanism, and the clamp is connected to the pull rope. There is a counterweight in the equipment installation shell, and a gas monitoring component is installed above the counterweight. The advantage is that: it can realize penetrating detection, and at the same time realize the sealing of the gap of the pipeline and the cleaning of obstacles inside the pipeline.

Description

technical field [0001] The invention relates to the field of coal mine gas test monitoring devices and methods, in particular to a coal mine gas test monitoring device and method. Background technique [0002] Mine gas refers to the general term for toxic and harmful gases mainly composed of methane, and sometimes refers to methane alone. Gas is lighter than air, is easy to diffuse and has strong permeability, and is easy to be released from the goaf through the rock formation from the adjacent layer. Gas itself is non-toxic, but it cannot be breathed by people. When the gas concentration in the air in the mine exceeds 50%, it can cause people to suffocate and die due to lack of oxygen. Gas can burn or explode, and gas explosion is one of the major disasters in coal mines. Therefore, the real-time detection of underground gas concentration has always been regarded as an important task to maintain safe production in mines. [0003] At this stage, the main improvement of co...
