A mud pan apparatus provided for use in combination with a well drilling device. The mud pan apparatus includes a housing having a bottom, opposed sidewalls and opposed end walls. Together, the bottom, sidewalls and end wall of the housing form a reservoir which is adapted to receive a slurry laden with earth deposits produced during the well drilling operation. A plurality of sprockets are rotatably mounted on opposite sidewalls of the housing and a chain that is provided around each set of sprockets. A plurality of space scrapers are secured to the chains so that the scrapers extend between the chains and thus across the bottom of the housing. A motor rotatably drives the pulleys which causes the scrapers to move along the bottom of the housing and up one side of the housing to thereby remove earth deposits from the housing and onto the ground.
