In order to improve the safety and reliability, and reduce development costs of the refuge chamber cabin, we combined TNT equivalent substitute with numerical simulation method, used software AUTODYN to carry on simulation calculation and obtain coal mine gas blast law and determine explosion shock loading. On this basis, four different refuge chamber cabin structure geometries based on stiffeners were designed , then the ANSYS Workbench platform software was used to perform dynamic simulation and safety comparative analysis for anti-knock properties of four different stiffeners refuge chambers, we obtained a mine refuge chamber structure with low-cost and good performance, which provided some ideas for mine refuge chamber’s research and development.

Aimed at the frequency gas accident of coal mine, we designed a coal mine gas monitoring system based on Arduino microcontroller. The MQ-4 gas sensor was used to collect gas concentration, wireless ZigBee was used to transfer data of gas concentration to PC. The system can display gas concentration real-timely by LCD and use SD card to store the data. The system will send out sound and light alarm when the gas concentration overruns. Industrial tests have been carried out in Wuyang coal mine. Results show that gas monitoring system can well adapt to environment of underground coal mine and the measurement is accurate. The system is real-time monitoring and early warning. It has the characteristics of low power consumption, low cost, wireless, good market prospect.

Performance of tool has always been a puzzle in the course of high manganese steel drilling. In this paper, improvement of drill tool is been done on drill bit structure and parameters of cutting tip by means of analyzing geometric parameter. By utilizing simulation method correctly, the influence of bit parameter on drilling force is analyzed. Meanwhile, by adopting the way of dividing into groups, comparison experiment between improved and no improved has been done. The comparison analysis of test results is carried out including tool life, wear and drilling force. The conclusion showed that the improved bit has better performance.
