DRILLING DEVICE FOR SURVEYING FRONT ROCK-MASS INTACTNESS OF TUNNEL FACE FOR TUNNEL CONSTRUCTED BY TBM AND METHOD USING THE SAME
A drilling device for surveying front rock-mass intactness of a tunnel face for a tunnel constructed by a TBM and a method using the same are provided. The drilling device includes a drilling assembly, a drill-attitude control assembly, a data monitoring assembly and a TBM-platform fixing seat. The drilling assembly is connected to a TBM hydraulic system to obtain power, to drill the rock mass by an alloy bit through rotation and translation thereof. The drill-attitude control assembly controls an angle, a direction and a position of a drill rod and maintains drilling accuracy and stability. The data monitoring assembly acquires and stores a drilling dynamic-response signal by a high-accuracy sensor and a data recorder, to analyze an intactness characteristic of the rock mass. The TBM-platform fixing seat mounts the drilling device on the TBM.
AUTOMATIC SCANNING SYSTEM FOR TUNNEL WALLS CONSTRUCTED BY OPEN-TYPE TBM
An automatic scanning system for tunnel walls constructed by open-type TBM, to realize the automatic, accurate, rapid and omnidirectional scanning of tunnel wall. The system comprises a three-dimensional laser scanner, a walking unit, a circumferential track, several connecting rods and a remote-control unit; wherein the three-dimensional laser scanner is fixed on the walking unit. The walking unit is provided on the circumferential track and configured to walk on the circumferential track at a set speed and a set number of walking cycles according to a control instruction. The circumferential track is fixed on the main beam of open-type TBM through the connecting rods and located between the roof bolter and cylinder of gripper shoe. The remote-control unit is configured to issue the control instruction and control the three-dimensional laser scanner to scan the tunnel wall and transmit the scanning data using set scanning parameters.

AUTOMATED MATERIAL INVENTORY AND DELIVERY SYSTEM FOR UNDERGROUND MINES
The invention discloses an automated material inventory and delivery system for underground mines using a shaft and hoist transporting material from the surface to working areas. The system includes means for automatically and paperless processing orders for supplies from a plurality of locations within the mine. The system communicates to client through a plurality of terminals located throughout the mine and tracks material received, stored and distributed using electronic inventory tracking means. Loading and unloading of material into and out of the cage is automatic and includes automatic guided vehicle means to gather the ordered material and deliver to the cage. The system includes means whereby consumable supplies are autonomously delivered to a working area to ensure sufficient material is on hand to meet production targets. Ore may be transported to the surface using the cage and ore containers, optimizing the use of the hoist and increasing mine production.
Stress-transfer method in tunnel with high ground pressure based on fracturing ring
A stress-transfer method in tunnel with high ground pressure based on fracturing ring. According to the stress source of the tunnel, fracturing by drilling holes to form artificial weaken zones in surrounding rocks, that's named fracturing ring. The fracturing ring is the weaken zone with some width, whose inner boundary is the protective circle. The fracturing ring with small width is called the cutting and interruption circle and the cutting or interruption arc. The radius of the protective circle is determined by setting a certain width of safety coal pillar barriers at the edge of a support body. The radius of the fracturing ring is determined by the surrounding rock structure and the stress conditions as well as the construction technology. Usually, the higher the stress, the wider the radius of the fracturing ring. The cutting and interruption circle or arc could cut off all of the targeted rock which transmits the stress.

Anchor bolt length determination method based on monitoring of roof rock stratum horizontal extrusion force
An anchor bolt length determination method based on monitoring of a roof rock stratum horizontal extrusion force includes drilling a borehole in the middle of a roadway roof to determine a surrounding rock fracturing scope by a borehole television. The method includes selecting the number and locations of horizontal extrusion force measuring points according to the surrounding rock fracturing scope. The method includes monitoring and recording a change of the horizontal extrusion force over time in the borehole by a device for monitoring a roof rock stratum horizontal extrusion force. The method includes selecting a location with the largest horizontal extrusion force as a center of a anchoring segment of an anchor bolt to determine a distance between the anchoring center and the roof. The method includes calculating a total length of the anchor bolt.
