2.2. Measurement of UTHS Subsidence. As the UTHS is inside the overburden, it is impossible to measure its exact amount of deflection. After the mining of working face 206, to monitor the relative movement between the UTHS and the surface during the mining of working face 207, we drilled a strata displacement-monitoring borehole Y1-1 inside the overburden strata of working face 206.
