Frame depth (RP - 2 RP - 3 RP - 4) is used to measure rock roof bundle for the purpose of operational control state of marginal array mining fixed roof bolting, to ensure safe mining operations. Control of the relative displacement and the displacement speed indicators necessary to establish trends in the development of rock deformation at an early stage.
Mine workings of coal mines. In accordance with the "Instruction on the calculation and application of roof bolting in coal mines of Russia" controls separation of roof rock is conducted on all the interfaces of developments, including the lava, in areas workings with different breeds, designs anchors, as well as in places most heavy maintenance of the conditions laid down when driving. Measuring station for monitoring bundles to load anchors are installed in 80 - 100 m.
The design of the frame - self - supporting. It allows you to move away from the use of dosylochnyh rods and the need of drilling the mouth of the hole. Thereby facilitates and speeds up installation.
