ABSTRACT
The appositeness of composite organization for higher mechanization, confirmed by the subsequent record of the flight-loading faces just described, receives further support from the spontaneous efforts made by management in another pit to proceed by stages towards a composite form of organization. Although production longwalls were conventionally organized, two development faces—one hewing and one cutting—had been successfully worked as composite bargains. A third development face had been prepared to open up a new area of the pit where production faces were ultimately to have flight-loading, power-pulling, and scraper-packing. Flight-loading was not used on the development face, since this would have meant giving considerable time to technical experimentation which would have slowed up the rate of development.
