Foreword
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.
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. Inspection Guidelines for Mobile Coal Stream Mechanized Sampling System
1 Scope
This document specifies the general inspection principles, establishment of inspection procedures, inspection procedures, quality control and Inspection records.
This document is applicable to the mobile coal flow mechanized sampling system and the stationary coal mechanized sampling system for reference.

GB/T 30730 Technical conditions for coal mechanized sampling system
3 Terms and definitions
The terms and definitions defined in GB/T 19494.1 and the following apply to this document.
3.1 External audit
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 audit
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 Routine check
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
The mechanized sampling system ultimately retains the ratio of the actual mass of the sample to the amount of coal represented by the sample.
