Coal mine trackless rubber tyred vehicle transportation operation procedures are urgent

Legal analysis: On the side of the newly excavated transportation roadway of new mines and production mines, there must be a sidewalk with a width of more than 1m (1m for mines transported by comprehensive mechanized coal mining and trackless rubber-tyred vehicles) from the height of the roadway ballast, and the height of the pipeline hanging shall not be less than that

When the width of the sidewalk of the existing roadway in the production mine does not meet the above requirements, a dodge potato shelter must be set on one side of the roadway, and the spacing of the two dodges shall not exceed 40m. The width of the dodge pot shall not be less than, the depth shall not be less than, and the height shall not be less than the dodge hole, and it is strictly forbidden to pile up materials in the dodge hole.

When the width of the sidewalk in the mine transported by trackless rubber-tyred vehicles is less than 1m, special safety technical measures must be formulated to strictly implement the regulations of "pedestrians do not drive, and no pedestrians are allowed to drive". On the upper and lower sides of the roadway at the parking place of people and vehicles, there must be a sidewalk with a width of more than 1m within the height from the roadway ballast, and the height of the pipeline hanging shall not be lower.

Legal basis: "Standardization Law of the People's Republic of China" Article 2 The standards (including standard samples) mentioned in this law refer to the requirements of those who need unified technical documentation in the fields of agriculture, industry, service industry and social undertakings.

Standards include national standards, industry standards, local standards and group standards, and enterprise standards. National standards are divided into mandatory standards and recommended standards, and industry standards and local standards are recommended standards.

Mandatory standards must be enforced. The State encourages the adoption of recommended standards.

Legal analysis: Rubber-tyred vehicles must purchase and use explosion-proof trackless rubber-tyred vehicles with safety marks for coal mining products, such as the MA certificate of the safety standard certification of Dichan Coal. Coal mines are strictly forbidden for non-explosion-proof motor vehicles to enter the mine without scattering and high, and strict requirements are also imposed on the personnel who operate rubber-tyred vehicles, and must have explosion-proof knowledge.

Moreover, when transporting underground workers in coal mines, it is strictly forbidden to use non-use. In fact, there are various different types of braking forms in the whole vehicle, not only in the explosion-proof vehicles in coal mines, but from the perspective of safety, it will be more appropriate and meet the relevant requirements to consider the braking form of explosion-proof rubber-tyred vehicles. Before talking about the principle of the hydraulic brake system of the explosion-proof transport rubber-tyred vehicle, let's take a look at several forms of hydraulic brakes.

1) Braking in driving: braking in the process of driving, it is mainly realized by controlling the drive hydraulic system.
