In addition to the initial and final subsidence surveys this monitoring <br /> schedule will result in the monitoring of active subsidence over panel 301L <br /> three times, over panel 302 four times and over 302L three times. <br /> Because of the rugged terrain, both men and surveying equipment will <br /> require helecopter transport to and from the proposed instrumentation area <br /> for each survey if efficiency and cost effectiveness are to be maintained. <br /> Task V - Date Analysis <br /> The data obtained from the proposed subsidence monitoring net will be <br /> analyzed and compiled in a' manner that will allow the formulation of an <br /> elementary prediction model . The data will be analyzed with respect to the <br /> mine geometry, overburden configuration and face location. Vertical move- <br /> ment, horizontal movement, subsidence development and the angle of draw will <br /> • be determined. <br /> Subsidence and strain profiles will be generated for each line of subsi- <br /> dence monuments after each survey of the monitoring net. These profiles will <br /> be superimposed on cross sections of the mining area and the mine workings . <br /> G <br /> • <br /> I <br /> 13 <br />
