Abstract

Due to the continuous development of underground mining methods, technical equipment, the Internet and intelligent technology, a new energy revolution will be of great significance in years to come. Meanwhile, the high-intensity mining (HIM) of thick coal seams has become an important development direction of China’s underground coal mining technology. By summarizing the current situation and analyzing the characteristics of underground HIM using the analytic hierarchy process (AHP) method in thick coal seams in China, negative externalities are proposed, which are mainly reflected in the three aspects of overlying strata, ground surface, and ecological environment under the premise of standard operating procedures and underground mining safety. Considering the negative externalities of overlying strata and surface damage in HIM, geological disasters under HIM are divided into mine production disasters and ecological environment disasters, which have cluster, suddenness, and chain characteristics. Based on the types and characteristics of geological disasters caused by HIM, coal mining technology for preventing major geological hazards and environmental damage has been formed, providing a theoretical guidance and technical support for the development goals of HIM and environmental protection in China.
