Abstract

The invention belongs to the technical field of coal mine safety, and discloses a three-level gas leakage evaluation system for a whole gas extraction system, and an evaluation method. The system comprises a bottom layer monitoring unit, a server, and a remote user unit, and further comprises a gas extraction drilling evaluation unit, a gas extraction pipe network evaluation unit and a gas extraction pump station evaluation unit which are all connected with the server, wherein the bottom layer monitoring unit is connected with the server; and the server is connected with a remote user unit. The method comprises the steps of pre-evaluating a gas extraction effect, establishing a model diagram of the whole gas extraction system, collecting gas extraction related information, evaluating the three-level gas leakage condition of the whole gas extraction system, and displaying the three-level gas leakage condition of the whole gas extraction system and an evaluation result. According to the three-level gas leakage evaluation system for the whole gas extraction system, and the evaluation method provided by the invention, the three-level gas leakage of the whole gas extraction system is evaluated, analyzed and visually displayed, so that the evaluation work is programmed, intelligent and visual, the gas extraction efficiency is improved, and safe operation of the gas extraction system is guaranteed. The three-level gas leakage evaluation system for the whole gas extraction system, and the evaluation method provided by the invention are suitable for three-level gas leakage evaluation of the whole gas extraction system.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety, and relates to gas drainage gas leakage evaluation, in particular to a gas drainage system-wide three-stage gas leakage evaluation system and evaluation method. Background technique [0002] At present, my country's coal consumption market is huge, and it is difficult to change the dominant position of coal in energy consumption in a short period of time. my country has gradually formed a new situation of joint mining of coal and gas. At present, the safe and efficient co-mining of coal and gas mainly adopts the method of pre-draining gas through drilling. However, due to the differences in geological conditions, occurrence conditions and extraction methods adopted in various regions, the evaluation of gas leakage in the entire gas drainage system It has the characteristics of high complexity and high challenge. [0003] The traditional evaluation of gas leakage in the gas drainage syst...
