October 7, 2008, by
- Mr. Justin
Sousa and
- Mr. Niels Rasmussen, of Thurber Engineering Ltd. (Thurber).
The Sis were read using an RST Digitilt probe with 2 ft wheelbase and an RST hand-held and SINCO Datamate readouts, respectively. Inclinometer reading depths were defined as per cable markings with respect to the top of the inclinometer cable clamps with the exception of SI99-4R, which was read from the top of the casing. 2 . I N T E R P R E T A T I O N 2.1 G e n e r a l Sl plots A and B directions are presented in Section D and are summarized below. Where movement has been recorded the resultant plot (X direction) and rate of movement have also been provided. 2 . 2 Z
