Problems solved by technology

Inductively analyzing these methods, there are mainly three deficiencies: First, most methods (such as multi-stage orifice flowmeters, rotameters, gas pressure gauges, and portable tile detectors, etc.) can only rely on the naked eye to read data. Long-term measurement, the highest value of the data is not easy to be captured, resulting in omissions, affecting the accuracy of the measurement results; second, the type of borehole gas parameter measurement is single, and it is impossible to measure multiple parameter data of the borehole gas at the same time, and co

Abstract

The invention relates to an outburst prediction and forecast device based on coal bed drilled hole gas parameter detection. The outburst prediction and forecast device comprises a collecting tube, the collecting tube is connected with one end of a hose, the other end of the hose is connected with an air inlet of an air chamber through a filtering device, and sensors are arranged inside the air chamber and connected with a processing circuit which is connected with a display screen. An air outlet of the air chamber is connected with an air outlet tube, an anti-explosion electromagnetic valve is arranged on the air outlet tube, and an exhaust hole is formed in the end of the air outlet tube. The coal bed drilled hole gas detection device can determine gas concentration, gas flow, gas temperature and gas pressure inside coal bed drilled holes at the same time, and the data are displayed in real time, continuously recorded and easy to inquire; an engineering technician under a coal mine can master the danger level of outburst at a determined place accurately in time, and technical supports can be provided for safe and economical exploitation of an outburst coal bed.

Description

technical field [0001] The invention relates to an outburst prediction and forecast device, in particular to an outburst prediction and forecast device capable of simultaneously detecting multiple parameters of coal seam drilling gas and displaying the results in real time. Background technique [0002] As we all know, coal and gas outbursts seriously threaten the safe production of mines. By drilling and measuring the gas parameters of the boreholes, it is possible to pre-judge the severity of coal and gas outbursts before mining operations, and provide technology for safe and economical mining of outburst coal seams. However, the risk of coal and gas outburst is controlled by various factors, and the gas parameter value of the borehole is also changing with time, and the working face needs to determine whether to continue the mining operation or not according to whether the coal body in front of it has the risk of outburst. Supplementary anti-outburst technical measures; t...
