NB/T 11120-2023Digital construction of underground coal mine—Technical requirements (English PDF)

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

This document gives the general requirements for the digital construction of underground coal mines, digital mine architecture design, and technical requirements to guide underground coal mines.

The mine applies computers, networks, information control, intelligence and coal mine production technology to carry out digital construction to realize the operation, safety and production of the enterprise.

The organic integration of management, equipment control, production decision-making and other information enables centralized control of all mechanical and electrical equipment in the mine, achieving less coal mine production Humanization (unmanned); applying information technology to realize scientific operation and management, optimize production planning, production safety scheduling, and production process control, and realize Today's mines are highly informatized, automated, efficient, safe and profitable.

The digitization of underground coal mines is the collection of information on various aspects of the mine's geographical location, production operations, safety conditions, equipment and management, etc.

Transmit, process and apply, and then transmit the collected information on production, safety, geography and equipment to the mine in real time through the communication network The ground dispatch center uses these data to make production management decisions and realize digital production.

Coal mine intelligence is a mine production operation based on automation and digitization, combined with computer technology and artificial intelligence theory. advanced mode. In an intelligent mine, first of all, each subsystem can be interconnected and controlled, and at the same time can operate automatically. Due to intelligent system operation The control is simple and convenient, thereby reducing the technical requirements for operators, not only saving time and effort, but also reducing the possibility of misoperation to a great extent.

Rate. For managers, the information they can get is more comprehensive, accurate and timely, which is helpful for managers to make correct decisions quickly. so, Automation and informatization are the foundation of intelligence, and intelligence is the goal of automation and digitization.

3 Terms and definitions

The following terms and definitions apply to this document.

4 General requirements

4.1 Digital mine construction should be based on reliability, advanced technology, platform selection, hardware selection, network design, support environment, and application system construction.

Sex is the principle. Redundancy design should be fully considered for key systems and equipment, and complete emergency plans should be considered in system design. From the following aspects To ensure the high reliability of the system.

a) Adopt distributed database and file system design and deploy multiple database systems and file systems according to actual application requirements;

b) For key equipment, use dual-machine or multi-machine hot backup technology to ensure intelligent detection and automatic switching;

c) For important storage and switching equipment, adopt redundant design, have automatic failover capability, and support online hot plugging;

d) The basic network architecture adopts link backup and implements load balancing technology to ensure link reliability and provide high-speed transmission bandwidth with a reserved area.

Provide a certain number of redundant links to prepare for fault handling;

e) Use advanced communication technology to enhance communication redundancy and improve the communication system's ability to withstand disasters to meet the needs of coal mine emergencies. Emergency communications.

4.2 The system design of digital mines mainly includes application architecture design, unified platform design, data interaction design between subsystems, and IT infrastructure design. Infrastructure architecture design, interface design, etc.

4.3 Digital mine construction must be compatible with multiple data sources on the premise of complying with current general standards. For different types of automation systems, Production and operation management systems with different requirements must be able to provide as many different types of interfaces at various levels as possible that comply with international standards.

Realize that the interfaces and transmission protocols between hardware and supporting software and between systems are the same or compatible with each other, fully ensuring that all subsystems maximize information sharing.
