Based on continuous optimization of analysis contrast of caving mining face roadway equipment layout, end support was cancelled, upward ventilation was employed, machine lane and track lane were located in return airway and intake airflow roadway respectively. As a result, transfer difficulty of reserved loader and end support caused by bottom mud were solved, interfusion of dust and gas was reduced in intake airflow roadway and working face, which improved production environment of working face.
