Introduction

Terminology is a collection of names used to represent concepts in a specific discipline. It is one of the basic elements of standards and is an important part of scientific research, teaching, and technology.

GB/T 7679 "Mining Machinery Terminology" is based on the current situation of China's mining machinery industry.

A complete set of mining machinery industry terminology standards compiled based on international standards and foreign advanced standards.

It is one of the important basic industries that provides equipment for the mining and processing of materials, materials and fuels. It covers a wide range of areas and has a wide range of products.

The varieties are divided into the following parts.

— Part 1: Mining equipment. The purpose is to define the terms and definitions of mining machinery and mining equipment.

— Part 2: Loading equipment. The purpose is to define the terms and definitions of mining machinery loading equipment.

— Part 3: Hoisting equipment. The purpose is to define the terms and definitions of mining machinery and mining hoisting equipment.

— Part 4: Mining transport equipment. The purpose is to define the terms and definitions of mining machinery and mining transport equipment.
