Summary of the completion and transfer of mining engineering materials

(1) Classification and summary of the completion of mining project data 1. Classification of mining engineering completion data Mining engineering completion data can generally be divided into: (1) engineering quality acceptance assessment data; (2) engineering quality control data; (3) engineering Safety and functional inspection data; (4) Engineering inspection quality inspection data; (5) As-built drawings.
2. Geological data and contents of mining project The geological data to be handed over by the mining project shall contain the geological data and hydrogeological data of the mine in addition to the general engineering geological data.
Mine geological data should be compiled into well construction geological reports, including geological exploration reports and on-site accidents, and mine reserves accounting.
Mine hydrogeological data includes:
(1) Hydrogeological observation accounts and results;
(2) Data related to the water inrush point, records, etc.;
(3) Cross-sectional view of hydrogeology in the wellbore and main roadway;
(4) Jianjing hydrogeological supplementary exploration results;
(5) Construction of hydrogeological report (can be combined with construction geological report).
3. General principles for the summary work of the mining project completion data (1) The summary and test papers should follow the natural formation rules of the project documents, maintain the organic connection of the documents in the volume, and facilitate the storage and utilization of the files.
(2) When a construction project consists of multiple unit projects, the project completion data shall be summarized and organized according to the unit project.
(3) Engineering quality control data, engineering safety and functional inspection data in project completion data are summarized and organized according to unit engineering, branch engineering, professional, stage, etc.; engineering quality acceptance assessment data, engineering inspection quality inspection data according to Unit engineering, professional and other summaries, group volumes; as-built drawings are summarized and organized by unit engineering and professional.
(II) Quality requirements for the completion data of mining projects 1. The project completion data shall be the original.
2. The content and depth of the completed data must comply with the relevant national technical specifications, standards and procedures.
3. The content of the project completion data must be true and accurate and consistent with the actual project.
4. The completion data of the project shall be retained for a long time, and shall not be written or printed with fading materials.
5. The completion data of the project should be clearly written, the drawings should be clear, the chart should be clean and tidy, and the procedures for signing and stamping should be complete.
6. The cover of the project completion data volume and the cover of the file should be made of 70g or more of white writing paper, and the A4 format should be used uniformly.

Metal Spiral Wound Gasket

Metal Spiral Wound Gasket

Description:It is the ideal gasket in the semi-metallic category. A narrow strip of V-shap metal hoop is spirally wound under tension with a filler cushion between the lami nation of the metal and is spot-welded at both ends. This kind of gasket`s Filler:graphite, PTFE, asbestos, non-asbestos.

Feature:

1.Little deterioration of the filler material at high temperature,oustanding long-term seal ability even under high temperatures and high pressures.

2.Especially gas sealing, is superior to that of Asbestos Gasket.

3.Sealing remains outstanding even under servere conditions such as pressure fluctuations and heat cycles.

4.Outstanding sealing even at cryogenic temperature.

5.Excellent seal ability is maintained making it possible to apply this for corrosive fluids by selecting the Appropriate materials.

Spiral Wound Gasket is widely used in the industries of Petroleum, chemical, electric power,shipbuilding, steel.
