The apparatus includes a generator for generating an air disturbance, and receiving means for locating adjacent the drill hole and receiving the air disturbance. A sensor is provided for sensing at least one parameter resulting from the received air disturbance. The apparatus further includes determining means for determining the volume of the drill hole using the parameter. Advantageously, the apparatus can accurately measure the volume of the imperfect drill holes irrespective of shape.1/3 100 112 102 114 106 110 116104 Generator Sensor 108 1118 Controller 118 126 120 122 Temperature Software 128 Processor Pressure Database 124 FIG. 1
