This document specifies the design loads and the design procedures for the design of rope guides and rubbing ropes used for guiding conveyances and preventing collisions in vertical mine shafts for permanent operations. It covers personnel and material hoisting, as well as rock hoisting installations. There are no fundamental limitations placed on the size of conveyances, the hoisting speeds, shaft layout configurations, or the shaft depth. This document can be applicable to shaft sinking operations when kibbles run on the stage ropes. There are many reasons, based on technical, timing, and cost factors, why rope guides are selected or not for a particular application, following careful assessment at feasibility stage of any project where rope guides are considered. This document provides some comments regarding the advantages and disadvantages of using rope guides compared to rigid guides, and specific design aspects for consideration when using rope guides. However, it is primarily intended to provide the technical information required to ensure good engineering of shafts where rope guided hoisting is the chosen solution. This document does not cover matters of operational safety.

ISO 19434:2017 establishes a classification of mine accidents by their origin or causes, by the type of accident, and by their results or consequences. The latter includes only the accidents resulting into consequences on people, not equipment or machinery. Different categories of causes, types and consequences of mine accidents are briefly defined, and a 3-digit code is assigned to each category. These can be combined to ultimately allocate a unique 15-digit code to each type of mine accident. This code can then be used in statistical analysis. Similarly, an allocated code clearly shows to which categories of causes, type of accident and resulting consequences the mine accident belongs to. ISO 19434:2017 is applicable to all surface and underground mines. NOTE: Accidents can be classified in terms of other items than those given in ISO 19434:2017, especially in researches and in other classification schemes. These can be, e.g. classifications based on the level of financial damages; gender, age, professional skills, terms of service and academic degree of the personnel; days of week, month, year, hour of accident; area of site, etc. While these classifications can be useful to enable certain decisions to be taken by the health and safety executives, they are not considered in ISO 19434:2017.

ISO 18871:2015 provides methodology for measuring coalbed methane content of coal core samples obtained by coring or sidewall coring during well drilling. It shall be also applied to drill cuttings samples, if the equipment for the determination of the coalbed methane content according to a respective national standard is not available. The selection of the most appropriate method shall consider the purpose of the test and the possibilities of sampling. ISO 18871:2015 is applicable for the direct method of measuring coalbed methane content. It includes sample preparation, experimental procedures and calculation methods. Indirect methods of measuring gas content of coal (not included in this standard) are generally based on either the gas sorption characteristics of coal under defined/specified pressure and temperature conditions. ISO 18871:2015 includes three types of direct measuring methods: conventional desorption (slow desorption) of core samples, fast desorption of core samples, fast desorption of cuttings or lump samples. The difference among them lies in the time allowed for gas to desorb before final crushing and in sample size and shape. ISO 18871:2015 is applicable for the determination of the methane content of coal during coal and coalbed methane exploration for the determination of free gas content of low rank coals is included.

EN 1127-2 specifies methods for explosion prevention and protection in mining by outlining the basic concepts and methodology for the design and construction of equipment, protective systems and components. This European Standard applies to Group I equipment, protective systems and components intended for use in underground parts of mines and those parts of their surface installations at risk from firedamp and/or combustible dust. This European Standard specifies methods for the identification and assessment of hazardous situations that may lead to explosions and describes the design and construction measures appropriate for the required safety. This is achieved by - risk assessment; - risk reduction. The safety of equipment, protective systems, and components can be achieved by eliminating hazards and/or limiting the risk, i.e. a) by appropriate design (without using safeguarding); b) by safeguarding; c) by information for use; d) by any other preventive measures. Measures in accordance with a) (prevention) and b) (protection) against explosions are dealt with in Clause 6 of this standard; measures according to c) against explosions are dealt with in Clause 7 of this standard. Measures in accordance with d) are not described in this European Standard. They are dealt with in EN ISO 12100:2010, Clause 6. The preventive and protective measures described in this European Standard will not provide the required level of protection unless the equipment, protective systems and components are operated in line with their intended use and are installed and maintained according to the relevant codes of practice or requirements. This standard is applicable to any equipment, protective systems and components intended to be used in potentially explosive atmospheres. These atmospheres can arise from flammable materials processed, used or released by the equipment, protective systems and components or from materials in the vicinity of the equipment, protective systems and components and/or from the materials of construction of the equipment, protective systems and components. As shot firing can release potentially explosive atmospheres, this standard is also applicable to the equipment used for shot firing, apart from the explosives and detonators. This standard is applicable to equipment, protective systems and components at all stages of use. This standard is not applicable to: - medical devices intended for use in a medical environment; - equipment, protective systems and components where the explosion hazard results exclusively from the presence of explosives or unstable chemical substances; - equipment, protective systems and components where the explosion can result from reaction of substances with oxidising agents other than atmospheric oxygen or by other hazardous reactions or conditions other than atmospheric conditions; - equipment intended for use in domestic and non-commercial environments where explosive atmospheres may only rarely be created and solely as a result of the accidental leakage of fuel gas; - personal protective equipment covered by Directive 89/686/EEC; the design and construction of systems containing desired, controlled combustion processes, unless they can act as ignition sources in potentially explosive atmospheres; - mines where firedamp and/or combustible dust are not naturally present and surface installations such as coal preparation plants, power plants, coke oven plants etc. in which an explosive atmosphere can be present, but which are not part of a coal mine. These are covered by EN 1127-1:2011.

This Technical Report gives additional and specific information on sampling for testing of waste from the extractive industry to support the development of appropriate sampling plans. This supplementary guidance to EN 14899 is required because waste from the extractive industry differs considerably from the waste types and sampling scenarios covered in the existing technical reports (CEN/TR 15310-1 to -5) that support the Framework Standard. This guidance document should be used in conjunction with EN 14899 and its supporting technical reports CEN/TR 15310-1 to -5.
The approach to sampling described in this document is primarily focused on the requirements to undertake mineralogical and geochemical testing of the waste. Whilst much of the background information provided is also relevant to geotechnical investigations there may be important additional requirements or differences in approach for determining relevant physical parameters. For example, many geotechnical parameters are determined using field tests, which are not discussed in this document. References to alternative source documentation are provided.
The guidance provided in this document applies only to above-ground exposure to radio-nuclides present in the undisturbed earth crust and not to the production, processing, handling use, holding, storage, transport, or disposal of radioactive substances that are or have been processed for their radioactive, fissile or fertile properties.
This Technical Report provides some discussion of current best practice, but is not exhaustive. To clarify the text, the document provides a number of worked examples in the Annexes.
