With the depth of coal mine increasing, it appeared a phenomenon of rapid floor heave in some roadways in a short time, which threaten greatly to the normal mine production and the lives safety of workers. The causes and control measures about rapid floor heave are analyzed in this paper. Which has a certain reference values for preventing and controlling rapid floor heave in deep mine.

Coal mine roadway deformation have a significant impact on coal mine production. Based on the Arduino microcontroller system and ultrasonic distance sensor, through temperature compensation and system fixes, designed a roadway deformation monitoring system which is high accuracy, low price and simple operation. Monitoring results through the LCD display, and SD card for data storage, the system achieved real-time monitoring of roadway deformation. The system was actually tested in coal mine, and achieved good monitoring results.
