      abstract = {This paper investigates the performance of a large multiuser multiple-input multiple-output (MU-MIMO) millimeter-wave (mmWave) communication system deployed in an underground mining environment. The study is based on empirical channel measurements conducted at 28 GHz using a base station equipped with 256 virtual antenna elements. Key channel parameters such as path loss, RMS delay spread, coherence bandwidth, and sum-rate capacity are analyzed. Results show that a multislope path loss model offers better accuracy than traditional models. The findings demonstrate the potential of massive MIMO in harsh underground environments for 5G and beyond.},
