Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1. Structure and Drafting Rules for Standardization Documents" drafting.

Introduction

This document is based on national safety production laws, regulations and standards, and draws on and absorbs international and domestic safety risk classification control and hidden danger elimination.

Relevant standard requirements for investigation and governance construction, as well as the construction and operation experience of dual prevention mechanisms for coal mines in recent years, combined with the safety production and management of the coal industry According to the actual situation of coal mine safety risks, the dual prevention mechanism (hereinafter referred to as the "dual prevention mechanism") has been clarified.

The complete idea and method of construction and operation. The construction and operation of the double prevention mechanism will help promote the "four transformations" of coal mine safety production. "Change", that is. from mainly treating the symptoms to treating both the symptoms and the root causes, and focusing on the root cause; from post-processing to pre-prevention and source treatment; from simple hidden dangers The transformation of investigation and governance to double prevention; the transformation from traditional safety management methods to information management methods, and effectively control safety risks in hidden dangers In the front, the investigation and treatment of hidden dangers should be put in front of the accident. This document aims to provide for coal mines to meet the connotation requirements of the dual prevention mechanism and cover different conditions. These elements together constitute a complete PDCA (Plan-Do-Check-Action) cycle.

The ring can support the effective implementation and continuous improvement of the dual prevention mechanism in coal mines, and continuously improve the company's safety governance capabilities. Coal Mine Safety Double Prevention Mechanism Specification
