Introduction
The coal mechanized sampling system mainly includes the moving coal flow mechanized sampling system and the stationary coal mechanized sampling system. However, in the coal machine
There are also problems in the construction and use of mechanized sampling systems, such as improper selection, untimely and irregular performance testing, and failure to detect in time during operation and management.
Problems and other situations affect the normal use and standardized operation of the mechanized sampling system.
The external verification and internal verification specified in this document mainly focus on whether the mechanized sampling system meets the requirements of the corresponding standards and whether it meets the
Inspection and evaluation based on specified operating conditions and design requirements. External verification can help evaluate the compliance, suitability of mechanized sampling systems
Usability and effectiveness; internal verification can help evaluate the effectiveness of the continuous operation of the mechanized sampling system, identify possible problems and improve them; operation
The inspection mainly focuses on the equipment, facilities and samples in all aspects of the entire process before each sampling operation of the mechanized sampling system, during the sampling process and after operation.
Inspection and evaluation of product quality can help discover problems existing in the daily use of mechanized sampling systems, infer the causes of problems and
Improve.

3.1
external auditexternalaudit
Personnel with corresponding professional capabilities and not directly related to the management and operation of the mechanized sampling system to be verified shall conduct inspections of the mechanized sampling system.
Inspection and assessment of compliance with the provisions of corresponding documents and system applicability.
Note. These documents mainly include GB/T 19494.1, GB/T 19494.2, GB/T 19494.3, GB/T 30730, etc.
3.2
internal auditinternalaudit
Technical personnel with corresponding professional abilities who are not responsible for the daily operation of this mechanized sampling system (such as sampling technology managers, technical personnel in charge
personnel, specialized workers, etc.) to inspect and evaluate whether the mechanized sampling system meets the operating specifications and operating conditions specified in the document.
Note. Operating specifications include performance test reports, procedures and work instructions formulated by the operating unit, operation and maintenance operation manuals and instructions provided by the manufacturer, etc.
3.3
Before, during and after each operation of the mechanized sampling system, the operators evaluate the operating conditions of the equipment and facilities in all aspects of the entire process.
and inspection of sampling conditions.
Note. Operators include those responsible for monitoring the operation of the sampling system, sample taking and collection.
3.4
sampling ratio samplingratio
FSR
The mechanized sampling system ultimately retains the ratio of the actual mass of the sample to the amount of coal represented by the sample.
