There are two broad types of roof as far as support is concerned, the immediate roof above the coal and the main roof. Artificial support for mining purposes is only concerned with the immediate roof as nothing except large blocks of solid coal, or massive concrete, will support the main roof. The immediate roof is generally a few feet thick but can vary from inches to 20 ft or more. 3, record 1, English, - immediate%20roof

Lorsqu’il s’agit d’un gîte épais, de forte pente, d’un minerai qui se fracture facilement et dont la faible valeur tolère quelques pertes, on emploie une méthode par éboulement du minerai, ou caving. La chambre-magasin devient une chambre d’éboulement, où le minerai tombe de lui-même au fur et à mesure qu’il perd l’appui des blocs éboulés lorsqu’on les soutire au bas de la chambre; parfois, on facilite cet éboulement en tirant des charges d’explosif. 8, record 4, French, - foudroyage
