Abstract
Based on the various problems in the process of coal robot applications, from three-dimensional analysis of the key technology, market demand, and policy regulations and standardization, the paper reviews the use of carbon fiber material, elastic material of traditional surface spraying and integral casting technology to realize lightweight robot, by using the dual redundant design to improve the reliability of the rescue robot CPU, through the functions of voice recognition obstacle sensor, gas sensor acquisition components, and distribution information to realize the underground rescue mission. In addition, virtual test technology, hardware in the loop simulation technology, and shrinkage model technology are proposed to solve the difficulties of hard field testing of rescue robots. These suggest that concrete measures have been pointed out to break the problem of the development of the coal mine relief robot.
Highlights
China has abundant coal resources and it is the largest coalproducing country of the world
The coal mine detection robot KQR48 developed by Tangshan Kai Cheng company and the coal mine rescue robot CUMTV developed by China University of Mining and Technology have obtained the Coal Mine Safety Certification (MA) and obtained the permission to enter the mine, but they have not participated in the actual rescue activities yet
Several countries have done much for the R&D of mine rescue robot in recent years, such as the United States, New Zealand, Russia, and China, with many problems appearing in this process
Summary
China has abundant coal resources and it is the largest coalproducing country of the world. Complex operating environment and lack of technology and management cause the fire, gas explosion, and other coal mines disasters. How to seize the best time to implement rapid and effective rescue and how to avoid and reduce the casualties caused by secondary accidents are a hot social issue in recent years. It has been more than ten years since the research of the mine rescue robots which were used to do the rescue work instead of human [2, 3]. Authors have reviewed developments of the mine rescue robots and problems encountered in the past ten years. This paper is prepared based on the development of the mine rescue robot in the past ten years
