Abstract: The paper analyzed main problems existed in integrated automation system of coal mine at present and proposed that goal of real-time control, precise management and scientific determination of physical mine would be achieved by use of mine Internet of things technology and its platform performance. It pointed out that three-layer architecture of mine Internet of things determines that mine Internet of things should naturally be an opening platform, which is divided into two parts namely structured platform and service platform. It proposed that the structured platform of mine Internet of things includes opening sensing platform, opening main transmission platform and opening basic application platform, and introduced the service platform of mine Internet of things according to actual request of coal mine including underlying service platform for distributed monitoring and control, public service platform for the third party, collaborative working platform of multi disciplines and cloud service platform. Finally it pointed out that the structured platform could ensure effective implement of the service platform, and the service platform is suitable for building a public platform for different mine disciplines to work cooperatively so as to form a new cooperative work model based on Internet of things, which is also benefit for integrating different services into mine Internet of things and promoting development of special services for mine safety production.
