In Jiuxin Mine, Zhao Guangyi learned in detail about the mine’s coal output, coal price, mine leaders’ entry into the shaft and shifts, underground personnel positioning, gas prevention, roof management, water hazard prevention, and coal mine intelligent construction, etc., and proposed safety production work Strict requirements.

　　Zhao Guangyi emphasized that doing a good job of coal mine safety production during the national "two sessions" is an important political task at present. It can be seen from the excavation engineering plan that Jiuxin has complex geological structure, many faults, difficult mining replacement, and particularly difficult roof management and water damage prevention. It is necessary to strictly implement the system of leading shifts and on-duty by mine leaders. Each shift inspects key locations and key links underground, and conducts checklist-type hazard investigations to correct irregular behaviors and unsafe factors to curb coal mine safety accidents. At the same time, it is necessary to focus on strengthening the "three preventions" work during the rainy season, and pre-deploy the investigation of hidden dangers of water damage prevention and control in wells, so as to ensure unsafe production and ensure the continuous stability of coal mine safety production during the "two sessions"
