Testing of Prototype Knee-Protective Devices

摘要

The purpose of the present study was to develop the prototype into a knee pad that would find a high degree of acceptance among coal mine workers. The result of the study is a knee pad design which rated second out of nine in the comparative evaluation. Also, the study outcomes were several recommended minor design modifications; recommendations for suitable production materials and methods; and larger range recommendations based on accumulated low coal mine experience regarding future miner's clothing and personal work, health, and safety equipment.
