BS ISO 4657:2022 煤层气资源评价规范

What is ISO 4657 - Assessment specification of CBM resources about? CBM is formed during the process of coalification by the transformation of plant material into coal. ISO 4657  is an International Standard that discusses assessment specifications of coalbed methane resources. ISO 4657  specifies the objectives, tasks, work processes, classification, report preparation, and acceptance of coalbed methane (CBM) resource evaluation. Who is ISO 4657 - Assessment specification of CBM resources for? ISO 4657 on assessment specification of CBM resources is useful for: The coal mining industry Coal mining management / contractors Distributors and suppliers of coal Chemical engineers Testing authorities

ISO 23872:2021 采矿结构-地下结构

This document specifies the design loads and the design procedures for the design of structures used in underground mines. It covers all steel and concrete structures used in underground mines, irrespective of the depth of the mine or the product being mined. This document adopts a limit states design philosophy. Typical underground structures covered by this document include, but are not limited to: — box front structures at the bottom of rock passes; — conveyor gantry and transfer structures; — chairlift support structures; — crusher support structures; — fan support structures; — fixed or retractable arresting structures for ramps (see ISO 19426-5); — foundations for pumps, fans, winches and underground winders; — high-pressure bulkheads; — monorails; — overhead crane gantries for workshops, pump stations and sub shaft winder chambers; — settler structures; — silo bulkhead structures; — silo structures; — structures supporting loose rock; — tip structures, including dump structures; — underground head frames; — ventilation control doors and other ventilation structures; — walls and floors for safety bays, refuge stations and sub-stations; — water control doors; — water retaining structures. This document does not cover matters of operational safety or layout of the underground structures.
