Due to the limitation of cost and time limit, the coal mining operation can usually be completed through cross-operation construction. Although this method can shorten the working hours to a certain extent, high risks also follow, which puts forward higher requirements for the safety management of underground work. Especially during the period of installation and withdrawal of fully mechanized coal mining face in coal mine, multiple types of work cooperate with each other, auxiliary transportation of explosion-proof vehicles, frame-type trackless rubber-tyred vehicles, battery cars, support vehicles and other vehicles cooperate with each other at the same time. Therefore, reducing the number of potential safety hazards caused by cross-operation has become the top priority of cross-operation safety management. This paper analyzes and summarizes the reasons for the frequent installation and withdrawal of fully mechanized coal mining face and the cooperation of multiple types of work with cross-operation, and formulates corresponding control measures, hoping to help improve the safety management level of coal mine electromechanical transportation and play a role in preventing accidents.展开更多
