Scope
GB/T 30730-2014 is the English-translated version of 煤炭机械化采样系统技术条件.
GB/T 30730-2014 sets the technical conditions for coal mechanization sampling systems.
Clause 1 states that the standard specifies the type, structure and main components of the equipment of the coal mechanization sampling system, referred to throughout as the sampling machine, together with technical requirements, test methods, inspection rules and signs, packaging, transportation and storage, and that it applies to coal flow sampling machines and to stationary coal samplers for coal-carrying trains and cars.
The table of contents runs 1 Scope, 2 Normative references, 3 Type, sampler structure and main components of the device, 4 Technical requirements, 5 Test methods, 6 Inspection rules and 7 Signs, packaging, transportation and storage, followed by three informative appendices on typical examples of the sampler, typical examples of the riffle and the determination of the maximum allowable deflection by a size exclusion test.
Clause 3.1 describes the basic structure as a sampling unit that takes the coal samples, an online sample preparation unit made up of feeder, crusher, riffle, coal receivers and reflow equipment for discarded material, with separator, mixer, screening equipment and balers in some configurations, and a control unit that coordinates the parts, with Figure 1 showing a one-stage and Figure 2 a two-stage online sample preparation arrangement.
Clause 3.2 divides samplers into mobile coal flow samplers, covering down-stream and across-the-belt sampling, and stationary coal samplers, which more often use a mechanical screw sampler, and 3.3 divides riffles into drop stream and across-the-belt types before the draft breaks off mid-sentence.
Both clauses state that other structures and types meeting the standard may also be used. Clause 2 cites GB/T 191, GB/T 985.1, GB/T 9286, GB 12348, GB/T 13306, GB/T 13384, GB/T 19494.1, GB/T 19494.2, GB/T 19494.3, GB/T 19867.1 and GB 50150.
The page records the standard as proposed by the China Coal Industry Association and administered by the National Standardization Technical Committee for coal (SAC/TC42). It was issued on 9 June 2014 and has applied since 1 October 2014.

Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Coal Industry Association.
This standard coal by the National Standardization Technical Committee (SAC/TC42) centralized.
1 Scope
This standard specifies the type of coal mechanization sampling system (hereinafter referred to as the sampling machine) structure and main components of equipment, technical requirements, inspection Test methods, inspection rules and signs, packaging, transportation and storage.
This standard applies to coal flow sampling machine and a stationary coal (coal-carrying trains and cars) sampler.

3 Type, sampler structure and main components of the device
3.1 Basic Structure
Sampler from the sampling unit, online sample preparation unit and control units. Sampling unit, including sampling, etc., in charge of coal samples taken; in Line sample preparation unit includes feeder, crusher, riffle, coal receivers, abandoned like flowback equipment, some online sample preparation unit further includes a separator, Mixer, screening equipment and balers, will be responsible for preparing coal samples taken; controls the operating unit is responsible for coordinating the various components of the sampling machine, complete mining Sampling and sample preparation capabilities.
Figure 1 is a phase of the online sample preparation sampler structure diagram, Figure 2 is a two-stage structural diagram of the online sample preparation sampler, in line with this Standard sampler other structures may also be used.
3.2 Sampler type
Sampler sampler coal flow into mobile and stationary coal sampler. Mobile coal flow down stream sampling includes sampling and sampling across the belt, Static coal samplers use more of a mechanical screw sampler. A typical example of the sampler shown in Appendix A, in line with the requirements of this Other types of samplers can also be used.
3.3 Riffle type
Riffle riffle stream comprising drop across the belt and riffle. A typical example riffle in Appendix B, in line with the requirements of this other
