Setting up the means of dust control in very high production level longwalls

Objetivo

This research tended to decrease the worker's exposure to dust by respecting the constraints imposed by the standards.

This progress does not require only solutions and new procedures, but also requires the improvement and the development of means and appareters.
This research succeeded in its main aim: improvement of worker conditions in very high production faces. In fact, these actions have permitted a decrease in dust problems for every worker.

The means aimed to this amelioration have agreed the uses; so, we can extend good principles to most of the equipment now in use, regarding the coal-faces.

This extension will continue until a complete standardisation of material and concerned methods.

In this way, a specific proposition concerning every coal-face equipment in coal-faces has been studied. It includes an optimal installation of dust control procedures.
The introduction of new generations of mining equipment (shearers operating at speeds of up to 8-9 m/min, conveyors with a capacity of 2 200 t/h) will bring further progress and even better performances in terms of instantaneous production.

Production levels of up to or even more than 3 000 tonnes per shift are conceivable.

Adequate dust control using existing means does not seem possible, taking into account the tighter constraints imposed by regulations to ensure workers' safety.

It is therefore necessary to improve the available means and investigate new means or methods of reducing exposure of workers to dust.

This project is concerned with research in this direction.

The project will comprise three parts:

- compilation of an inventory of available means of analysis of their characteristics,

- modification of technical means to make them more efficient and facilitate their use,

- study of organisational aspects.
