Abstract:The roadheader is widely used in coal mines in China， but most of the drivers of roadheader are directly exposed to the working environment， and the personal occupational safety and health protection is simple. According to the production practice of driving face in coal mine， combined with the specific characteristics of the comprehensive driving machine， a set of comprehensive safety protection facilities of roadheader were de veloped ， which included drivers5 room of roadheader， local cooling device， visual safety auxiliary device ， cable haulage of roadheader and smart roadster of transfer machine. The drivers5 room of the roadheader ensures that the only roadheader driver in the driving face was in a relatively closed unit， which could effectively avoid accidents such as small roof fall， coal and gas outburst， and had the functions of dust prevention， gas intrusion prevention ，noise prevention， moisture-proof and self-help. The local cooling device powered supply by compressed air and water has the characteristics of safety， environmental protection， economic reliability， energy saving and comfortability. In the high temperature season in summer，the temperature drop in the drivers5 room could reach 7 ~9 °C ， and the body temperature of the driver could be constant at 25 ~28 ℃ . The utilization of visual safety auxiliary device provided a good vision for the driver of roadheader and ensured the engineering quality of the roadways under construction. The using of irregular cable hauling device of roadheader and small sports car of transfer machine could reduce the number of working personnel in the driving face during coal cutting，and realized single operation within 50 m during the comprehensive excavation of the driving face. The comprehensive safety protection device for drivers of roadheader has been widely used in many coal mines. The occupational safety and health of drivers has been changed from passive protection to active prevention，which greatly improved the working environment of workers，reduced the possibility of accidents，improved the working efficiency ，and increased the working happiness of workers.
