###### Abstract
For example, the conveyor belt in the main belt roadway was frequently damaged by rockbursts, disrupting the normal production process of the mine. The main roadway in a mine needs to function in order to be used during the mining of all the coal seams for a long time. It plays a crucial role in transportation, pedestrian passage, ventilation, and power supply, etc. At present, there are relatively few studies related to rockbursts in main roadway. The reasons for the occurrence of rockbursts in main roadways are still unclear and relevant prevention methods are still lacking. Once a rockburst occurs in the main roadway of a mine, the services offered by that roadway including transportation, pedestrian passage, ventilation, and power supply, etc., will all stop, which seriously affects the normal production process of coal mines [6; 7]. Research on the prevention of rockbursts in main roadways has gradually become the key to sustaining the normal production process of mines, and rockburst mechanisms and prevention methods are also important scientific issues that urgently need to be addressed in regard to the current mining industry. In recent years, scholars from various countries have primarily focused their research on the prevention of rockbursts near the working face, with relatively little attention given to the mechanisms and management of rockbursts in main roadways [8; 9; 10; 11; 12; 13; 14; 15; 16; 17]. [PERSON] et al. [18] studied the superposition effect of stress induced by main roadways themselves. They attempted to use a kilometer drilling rig to perform deep-hole fracturing on the target rock layer to reduce the risk of rockbursts in main roadways. [PERSON] et al. [19] studied the influence of abutment stress near the goal and roof strata activities on rockbursts in main roadways and developed a stress relief plan, which included optimizing the location of the main roadway and carrying out deep-hole blasting of the roof strata. [PERSON] et al. [20] studied the reasons for frequent rockbursts in main roadways and segmented hydraulic fracturing technology for use in a horizontal, long borehole was implemented to relieve the stress around the main roadways. [PERSON] et al. [21] adopted methods such as optimizing the width of protective coal pillars, deep-hole blasting of the roof strata, and coal seam drilling, to prevent rockbursts. When rockbursts occurred in main roadways, the distance between the main roadways and the working face being mined was usually over 500 m. Often people did not think that mining activities at such a long distance away were the reason for the rockbursts in main roadways. Therefore, most studies on those rockbursts focused on researching the stress concentration within the main roadways and their geological and mining conditions that lead to that stress concentration. However, many rockbursts in main roadways basically only occur when there are mining activities around them. At present, there are very few studies on the impact of working face mining on rockbursts in main roadways. Especially due to the lack of effective analysis methods, the causes of rockbursts in main roadways under the influence of mining are still unclear and effective prevention methods have not been established yet. Therefore, the first research objective of this paper is to study the laws and reasons for the occurrence of rockbursts in main roadways under the influence of mining at working faces. Based on previous research, this paper describes two cases of rockbursts in main roadways, namely, when a working face was being mined facile the main roadway and when a working face was being mined parallel to the main road way, respectively. Occurrence laws on strong tremors and rockbursts in main roadways at different mining stages of near working faces were studied through seismic velocity tomography and the analysis of microseismic spatial activities and energy cloud evolution. The second research objective of this paper is to establish effective methods for preventing rockbursts.
