TH40813B - Ceiling collapse measuring device and tunnel wall - Google Patents

Abstract

DC60 (12/04/53) The ceiling and tunnel wall collapse measurement device consists of three key components: struts, leveling, measuring unit and hydraulic system. It was designed under the concept of solving problems. of old equipment The new invention was able to measure the collapse of the roof and wall of the tunnel in both vertical and horizontal easily and quickly Because it is lightweight, strong, durable and does not require maintenance. Vibrations that occur while measuring due to the activity of The mine is absorbed by a piston system that floats on the hydraulic oil, enabling fast and accurate readings, i.e. it reduces the vibration of the needle in the gauge. In addition, this new invention also Can be disassembled into 3 main pieces, a device that can be carried into a tunnel or mine channel easily The two main components of this new invention bring the existing equipment widespread to customize The production cost is much cheaper than the old inventions. The ceiling and tunnel wall collapsing measurement device consists of three key components: struts, leveling, measuring unit and hydraulic system. It was designed under the concept of solving problems. of old equipment The new invention was able to measure the collapse of the roof and wall of the tunnel in both vertical and horizontal planes easily and quickly Because it is lightweight, strong, durable and does not require maintenance. Vibrations that occur while measuring due to the activity of The mine is absorbed by a piston system that floats on the hydraulic oil, enabling fast and accurate readings, i.e. it reduces the vibration of the gauge in the gauge. In addition, this new invention also Can be disassembled into 3 main pieces, a device that can be carried into a tunnel or mine channel easily The two components of this new invention take the equipment that is already in use. It is widely used to make the production cost much higher than the old inventions.
