3 Basic regulations

3.1 The waterproof gate project should be designed by a unit with corresponding qualifications according to the mine hydrogeological conditions and water safety requirements.

The design should follow the principles of safety, reliability, and technical and economic rationality.

3.2 The construction of the waterproof gate should be reviewed and approved by the main person in charge of the coal mine, and the project should be completed by the chief engineer of the coal mine before being put into use. acceptance.

3.3 Technical documents such as corresponding technical standards, construction organization design, installation plan, safety technical measures, etc. shall be prepared before the installation of the waterproof gate.

3.4 All kinds of mechanical equipment, electric control equipment, parts and main materials in the waterproof gate and its control system, and its measurement, testing equipment, instruments Instruments, meters, etc., should comply with relevant regulations such as coal mine safety regulations, and their accuracy levels should meet the accuracy requirements of the tested items.

3.5 During the construction of the waterproof gate project, the quality of the project shall be inspected and recorded. For concealed works, inspection should be carried out before the works are concealed And make a record, only after passing the construction can continue. During the acceptance of the project, the acceptance and necessary random inspection shall be carried out on the basis of the relevant records.
