Coal bed high-pressure water injection intelligent monitoring system and intelligent monitoring method thereof

Abstract

The invention discloses a coal bed high-pressure water injection intelligent monitoring system and an intelligent monitoring method thereof. The high-pressure water injection intelligent monitoring system comprises a monitoring sensing system, a water pressure supply system and a central control mechanism. The high-pressure water injection intelligent monitoring method is based on the high-pressure water injection intelligent monitoring system and aims at monitoring the high-pressure water injection system in real time; the monitoring sensing system sends the collected data information to the central control mechanism, and judges if states of 'branch water escape', 'ultra-low flow rate, ultra-low water pressure', and 'early warning for water shortage' appear, and detect the water injection coal bed crustal stress in real time; the central control mechanism processes and analyzes the information and then transforms it to the control signal, and controls the monitoring sensing system and the water pressure supply system. Therefore, the influence of 'water escape', 'ultra-low flow rate, ultra-low water pressure' and other phenomenon on the coal bed high-pressure water injection is effectively reduced, and the water injection effect is effectively improved.

Description

technical field [0001] The invention relates to a coal seam water injection monitoring system, in particular to a coal seam high pressure water injection intelligent monitoring system and an intelligent monitoring method thereof. Background technique [0002] With the continuous increase of coal mining depth and the gradual improvement of mechanized production level, the hazards of natural disasters such as dust, rock burst, coal and gas outburst, and ground temperature in the coal mine production process are constantly escalating, especially coal mining dust, The rock burst hazard seriously threatens the safe production of mines and the physical and mental health of miners. [0003] Practices at home and abroad have proved that coal seam water injection is an effective method to fundamentally solve safety problems such as dust, rock burst, coal and gas outburst, and has played a very good role in the prevention, control and treatment of underground regional hazards. Pre-in...

Problems solved by technology

[0004] However, as a comprehensive disaster management technology, high-pressure water injection in coal seams lacks research on intelligent monitoring and control, resulting in poor coal seam water injection effects in Chinese coal mines
