Final answer:
Nonel MS connectors are used in mining and construction to safely initiate explosives, by joining lengths of shock tube for precise detonation.
Step-by-step explanation:
The purpose of Nonel MS connectors is to provide a safe, simple, and efficient way to initiate explosives in blasting operations, primarily used in the mining and construction industries. Nonel stands for Non-Electric and the MS connector is a means to securely and quickly join lengths of shock tube, which is a small-diameter, hollow plastic tube filled with a reactive substance. When initiated, the substance inside the shock tube detonates along the entire length of the tube at a speed of approximately 2,000 meters per second, which safely initiates the explosion of the connected detonator and explosive charge.
