3 Terms and definitions
The following terms and definitions apply to this document.
3.1
coal mine TBM coalmine TBM
By rotating the cutterhead and pushing forward, the roller cutter squeezes and crushes the rock, and the entire section of the coal mine tunnel is excavated and formed at one time, integrating exploration, excavation, support and transportation.
A general term for a complete set of equipment.
3.2
TBM driving in coal mine
A construction method for coal mine tunnel excavation using coal mine TBM.
4.Construction Preparation
4.1 Data Collection
Before construction, it is necessary to collect information related to the project and equipment, consult relevant designs, drawings, documents and geological data, and master construction technology, support
Requirements on methods, quality and acceptance, etc.
4.2 Detection work
Geological exploration should be carried out in advance according to the design and DZ/T 0215 requirements, and the geological data of the construction area should be established and improved.
Dynamically review the data to meet the requirements of TBM construction in coal mines.
4.3 Procedure preparation
In preparing construction operation procedures, it is advisable to comprehensively consider geological conditions, construction methods, selection of main equipment and supporting facilities, construction period requirements, safety measures, etc.
