Coal seam interior gas parameter measuring probe and using method thereof

Abstract

The invention relates to a coal seam interior gas parameter measuring probe and a using method thereof. The coal seam interior gas parameter measuring probe comprises a conical head, a pressure measuring pipe, a first probe main pipe and a plurality of second probe main pipes, wherein the conical head, the pressure measuring pipe, the first probe main pipe and the multiple second probe main pipes are detachably connected in sequence from left to right. During construction of the coal seam interior gas parameter measuring probe, the workload is few, due to extruding of a coal body and the probe, the self-sealing effect can be achieved after the probe is nailed into the coal body for a certain distance, it is guaranteed that the real gas pressure of the position where the probe pressure measuring pipe is located can be measured, and the time needed for measuring is short. According to the coal seam interior gas parameter measuring probe and the using method thereof, the gas pressure measuring period can be shortened, the pressure measuring success rate can be increased, the destroyed types of coal can further be judged through the nailing difficult and easy level in the process that the measuring probe is knocked into the coal body to provide a basis for gas relevant parameter measuring, and the coal seam interior gas parameter measuring probe and the using method thereof are high in practicability and worthy of being popularized.

Description

technical field [0001] The invention belongs to the technical field of coal mines, and in particular relates to a probe for measuring gas parameters in a coal seam and a method for using the same. Background technique [0002] At present, the measurement methods of relevant parameters of coal seam gas have various defects. For example, the current measurement of coal seam gas pressure can only be carried out by drilling and sealing holes in the coal seam. This method has a large construction workload and a long measurement period. The effect of sealing holes is difficult to guarantee, and the pressure cannot be measured due to easy air leakage; the coal body hardness measurement needs to be sampled in the coal seam and tested by the drop hammer method in the laboratory, and its disadvantage is that the workload is large and the error is large; The degree of damage can only be judged by observation, which has large errors, strong subjectivity, and cannot be quantitatively ref...
