I dont know how to understand the "drifts" and so the phrase "in a series of drifts" in the below sentence. Please help me clarify it. Thank you.
"In the SEM, tunnel excavation and support is typically performed in a series of drifts, depending on the anticipated ground conditions, which are sequenced to develop successively larger openings."

Comment: "Thank you for your help! I also guess this meaning but I am not confident. I also share that after checking with the client, they say drift is a tunnel open at one end only."
