摘要： This invention relates to a measuring and display system for loads applied upon digging blasted earth, which can contribute to accurate blasting. An operating direction of a bucket of an excavator is detected by pressure switches 15,16, while a pressure P.sub.B in a bottom compartment 6S.sub.B of a bucket cylinder is detected by a pressure sensor 17. A processor 23 computes a digging position based on signals from a boom angle sensor 18, an arm angle sensor 19, GPS 20 and a magnetic direction sensor 21, integrates pressures P.sub.B during an ON period of the pressure switch 15, and transmits the thus-integrated pressure together with the digging position to a computer 30. The computer 30 displays a map of a lot under blasting and blasting positions on a display, and on the map, also displays the thus-transmitted digging position by a mark X and the integrated pressure by a numeral. With reference to this integrated pressure, a determination is made as to whether the blasting was proper or improper. The results of this determination are used for the next blasting.
