Abstract: The present invention relates to a loaded-to-frame detection equipment for backfill grouting of a shield tunnel, including an automatic loaded-to-frame transmission apparatus, a ground penetrating radar, and an intelligent backfill grouting processing and analysis software. The equipment is integrated by using software and hardware, and can implement real-time visual detection of a backfill grouting layer in a shield construction process. The loaded-to-frame automatic transmission apparatus mainly includes a track, a synchronous belt, a transmission mechanism, a servo machine, and a drive and reducer; and a new air-coupled radar detection apparatus is carried on the loaded-to-frame automatic transmission apparatus and is installed on a shield frame. With the shield performs tunneling, circular detection on a grouting body of the shield and visual layered display of the grouting body are implemented.

Abstract: A system and method for drilling a borehole using a drilling rig having a rotary drill bit includes monitoring one or more drilling parameters; determining whether the one or more monitored drilling parameters are within predetermined specifications for one or more of the monitored drill parameters; and, executing an exception control procedure for control of a drilling parameter. The exception control procedure receives an input sensor value associated with a drilling parameter and applies feedback control to establish a scaled error value that is used to compute a setting value for the drilling parameter. The drilling parameters controlled may include the rotation speed of the drill bit, the feed rate of the drill bit, the weight-on-bit, or rotation torque during retraction of the drill bit. A computer-readable database of specifications of drill bits may be provided as a part of the system.

Abstract: An arrangement and method of utilizing rock drilling information in a mine whereby drill holes are drilled in a surrounding rock material by a first mining vehicle. During drilling measuring data is produced and is inputted to a monitoring device for analyzing procedures. The monitoring device produces rock condition data of the rock material being drilled. The produced rock condition data is then implemented in a second mining vehicle.

Abstract: The present invention relates to a surrounding rock pretreatment method for a TBM (tunnel boring machine) passing through a round tunnel section with high rock-burst risk. A technical solution of the present invention is as follows: the surrounding rock pretreatment method includes the following steps: 1. determining a pretreatment area, wherein an area in which a clear spacing between a to-be-constructed tunnel and an adjacent existing tunnel in a TBM tunneling direction is less than 2 times that of a tunnel diameter of the TBM to-be-constructed tunnel is the pretreatment area: 2. performing controlled blasting; 3. injecting high pressure water, and selecting part of blast holes I to perform cyclic water injection pressurizing; and 4, performing normal tunneling by the TBM.

Abstract: A method and apparatus for forming a tunnel structure at a relatively shallow depth from the surface, which tunnel can be used as a replacement or additional transport route to an existing transport route (2) which is already formed on the surface. The method comprises the steps of forming two spaced apart access tunnels, installing piles (15), installing slide tracks (17) in each of the tunnels, removing a part of the tunnels (hatched portion) to expose the tracks, introducing units (22) comprising side walls portions (26, 28) and a roof section (30) by moving the units along the tracks while excavating the soil in which the tunnel is to be formed is in advance of the leading edge of the units.
