This specification is applicable to the design of hydraulic retaining walls in hydroelectric power projects.
This standard applies to new or expanded photovoltaic power stations, as well as distributed photovoltaic power generation projects with an installed capacity of 1MWP or more and connected to the public power grid. Other photovoltaic power generation projects can refer to and use this standard for guidance.
This standard is applicable to the basic drawing of hydropower projects.
This document specifies the requirements for the support design, support materials, support construction, construction quality inspection, and support quality monitoring of the full-length anchoring and pre-stressing anchor cable support technology for mining. This document is applicable to mines using full-length anchoring and pre-stressing anchor cable support systems.
This document specifies the general requirements for the application of active explosion suppression devices and active explosion isolation devices in coal mines, as well as the installation requirements and maintenance and management of these devices.
This document is applicable to the application of active explosion suppression devices and active explosion isolation devices in coal mines.
This standard is applicable to the engineering design, construction, acceptance, and operation and maintenance of distributed photovoltaic power generation systems.
This document establishes the technical specifications for the backfilling of coal gangue, stipulates the requirements for the classification of coal gangue, the admission of coal gangue, the selection of sites for coal gangue backfilling, the feasibility analysis of coal gangue backfilling, the implementation of backfilling projects, and the environmental monitoring of backfilling projects.
This document is applicable to coal gangue or modified coal gangue used to replace sand, stone, and soil in the process of land rehabilitation. It provides available backfilling materials for land rehabilitation, land reclamation, land development, and land restoration, such as pit backfilling, infrastructure construction, and land creation in natural depressed areas. Other applications of coal gangue backfilling can refer to this document for guidance.
This document stipulates the applicable conditions, system layout, components of filling and mining equipment, process requirements, surface deformation, and underground mine pressure monitoring for paste-filling mining technology in coal mines.
This document is applicable to improving the recovery rate of coal resources, safe mining of coal under the "Three Reductions and One Increase" policy, recovering pillar-type and strip-type residual coal resources, ecological protection of mining areas, and harmless treatment of solid waste such as coal mine gangue and construction waste.
It is suitable for new or expanded photovoltaic power stations, as well as distributed photovoltaic power generation projects with an installed capacity of 1MWP or more that are connected to the public power grid.
