This act (with/without/or its amendments) is sometimes referred to as the COLOUR BAR or the COLOUR BAR ACT. The term colour bar, however, usually refers to a group of labor practices, informal trade union practices, government regulations, and legislation, all of which were developed over time to prevent blacks from competing for certain categories of jobs monopolized by whites.^{[citation needed]}

At any rate, this act included various regulations which gave "white workers a monopoly of skilled operations". However, The Act did not specify that blacks should be discriminated against in any way. Indeed, it made no mention of race or colour. Nor did it specifically and clearly give the government Mining Engineer powers to introduce a legal colour bar. But under section 4(n) it gave the Governor-General powers to grant, cancel and suspend certificates of competency to mine managers, mine overseers, mine surveyors, mechanical engineers, engine-drivers and miners entitled to blast. It also gave him the power to decide which other occupations should be required to possess certificates of competency.^{[citation needed]}

Some or other commission had criticized mine managements for employing large numbers of unskilled whites 'often entirely ignorant of mining, and whose principal and often only recommendation is their physical fitness and their suitability for rough work'. Yet when the commission reported in 1910, it submitted draft regulations that were heavy with colour bars. Some appeared in the interpretation of terms, as when the words 'white person' were inserted in the definition of banksman, onsetter, ganger and mine manager. Some took the form of an injunction to employ only whites in specified occupations, such as blasting, running elevators, driving engines, supervising boilers and other machinery; or as shift boss and mine overseer. Furthermore, only whites would be allowed to obtain the certificates of competence required, for instance, by engine drivers and boiler attendants. With some modifications, these draft regulations served as model for the MINES & WORKS REGULATIONS ACT of 1912.^{[citation needed]}

In contrast to the 1912 REGULATIONS, this Act bracketed Coloured with whites in a position of privilege. For there was no question of segregating the coloured who spoke the Afrikaner's language, shared his outlook and stood closer to one than to the black population. Furthermore, the key section of this act "stated that the minister, before announcing regulations for issuing certificates of competency (including the key blasting certificate, for nearly a century of license of the white miner), should seek the advice of the owners and of the organizations whose members hold a majority of the certificates, that is, the white unions, including the Mine Worker's Union. He was to do this through the formation of advisory committees." This act was further revised in 1956 to deal with the declaration of work in the national interest.^{[citation needed]}
