1. A coal and gas outburst monitoring device, comprising:
gas concentration sensors evenly arranged within a coal mine roadway, and used for monitoring the gas concentration at region ranges in real time;
temperature and humidity sensors distributed within the coal mine roadway; wherein, wind direction sensors are provided within the coal mine roadway;
an insertion and anchoring assembly, vertically inserted and distributed on a sidewall of a surrounding rock of the coal mine roadway; wherein the insertion and anchoring assembly is configured for monitoring stress change data in the sidewall of the surrounding rock in real time;
a pump drainage and monitoring mechanism, erected within the coal mine roadway;
wherein the pump drainage and monitoring mechanism is configured for cooperating with the insertion and anchoring assembly to perform a gas pump drainage monitoring for the sidewall of the surrounding rock of a goaf, to obtain gas seepage monitoring data in a surface layer and an inner layer of the sidewall of the surrounding rock;
a voice alarm and the alarm light, correspondingly distributed at a wellhead and a working face, which is used to issue a warning alarm;
a central monitor system, having data storage, a real-time display, an alarm triggering, and data analysis; wherein the central monitor system is combined with a data analysis software, a database mechanism, and data visualization tools to analyze gas concentration monitoring data in the coal mine roadway.
