Abstract This research aims to develop an innovative gas warning system for improving production safety in the underground coal mining industry. Coal mining is an important sector for China’s economic development; gas monitoring systems are widely adopted as almost 60% of coal mining accidents are caused by gas. Existing gas monitoring systems mainly focus on simply detecting real-time data obtained from gas sensors. The literature review did not find gas monitoring systems that provide alarms or warnings from the correlation of gas with data from other sensors. This research aims to fill this gap to uncover hidden patterns and correlations between gas and temperature, wind, and dust, and incorporate data analytics into developing an innovative, integrated gas warning system. Correlational research was adopted using 328,320 data outputs obtained from ZhongXing Co. Ltd in Dec 2019. The study found strong relations between gas and temperature, wind, and dust. A Triple-Correlation Theoretical Framework and a Unified Modeling Language (UML) model were developed for an innovative gas warning system. As a result of this research, the ZhongXing Innovative Gas Warning System was developed and deployed for user acceptance testing on 28 Aug 2020.

In Industry upset, gas detecting innovation discovers its significance where gas sensors utilized for identifying the dangerous gases. This has been created and changed slowly to improve its sensitivity and selectivity. Convenient and exact checking of combustible and risky gases inside the mines can help averting mishaps. Different wired and remote correspondence with the sensor hubs like Zigbee. Convention have been built up in later part and executed with Internet of Things (IoT) yet with impediments. In this paper the MQ2 gas sensors exhibit utilizing basic technique is proposed for better sensing and alterability the Node MCU (ESP8266) is utilized as a Wireless Fidelity (WiFi) module. The proposed work could build selectivity and better proficiency the undertaking expects to coming about a superior danger the executives framework.We incorporated how node mcu and ardunio are used for the advanced gas monitoring systems.
