Abstract

The invention relates to an intelligent coal seam gas pressure tester, which can effectively solve the problems of an instrument for testing the pressure and pressure change law of coal seam gas. A pressure sensor is arranged in a pressure testing room of the conventional pressure testing pipe and is used for transmitting a signal to a singlechip through a data line, and the singlechip is analyzed by using a computer, so that the pressure parameter and pressure change law parameter of coal seam gas can be obtained, and measured parameters are safe and reliable. The pressure tester plays an important role in guiding safe production of coal mines. The pressure tester has a simple, novel and unique structure, saves a large amount labor force and time, is an innovation in the coal mine industry, and has large social benefit and economic benefit when being popularized and applied.

Description

technical field [0001] The invention relates to the field of coal mine safety, in particular to an intelligent coal seam gas pressure tester. Background technique [0002] At present, coal mines around the world test the original gas pressure of coal seams by drilling holes into the coal seam, running casing, installing pressure gauges, and using people to observe the changes in the pressure gauges to test the original gas pressure of coal seams. This test method cannot record the change of gas pressure in real time, and the test will cause errors due to individual differences. An intelligent coal seam gas pressure tester that can observe and record in real time is urgently needed. Contents of the invention [0003] In view of the above situation, the object of the present invention is to provide a new type of testing instrument, which can realize real-time observation and record the changes of gas pressure and gas pressure and other parameters. [0004] The present inven...
