Abstract The present invention relates to a data acquisition system that allows estimating: a drilled distance, an inclination or angle of the drill rods and a drilling speed in a drilling machine during the drilling process in mining tunnels. The system comprises means that generate signals, preferably electronic devices that generate data, distributed throughout the structure of a mining drilling machine, and that, at the moment that said machine begins to carry out the drilling exercise, said signals are sent and compiled by an embedded computer and then processed to obtain the estimates of distance, inclination and drilling speed of said machine. The system comprises: at least one reference node, at least one mobile node, and at least one sensor that performs a measurement or generates data between nodes and at least one reading means of the measurements or data generated by the sensor between nodes, preferably an analog reader that measures electricity consumption. Measurements or data are processed to obtain estimates of drilling distance, inclination (angle), drilling speed and number of shots that are made in mining tunnels. 25 Date Recue/Date Received 2020-12-15
