Abstract: The auxiliary inclined shaft yard of Qinyu Coal Mine has been excavated, so it is necessary to construct the intersection
at the junction of the yard. In order to ensure the speed and efficiency of driving, the drilling and blasting method was adopted.
This paper introduced the construction scheme and support method of the crossing point in detail, and briefly introduced the safety
measures taken, which can provide a reference for the construction of the crossing point in the shaft yard under similar conditions.
