Мощный крутой пласт полезного ископаемого раздел ют на выемочные пол 1, вкоторых, провод т подготовительные выработки . Шаст отрабатывают сло ми 2 либр в нисход щем пор дке с закладкой выработанного пространства или обрушением кровли, либо в восход щем пор дке с закладкой выработанного npocfpatt-J .ств Каждый слой по его ширине-раздел ют на две полосы 3, 4. Ширину каждой полосы принимают равной половине мощности пласта. Полосы в пределах каждого сло отрабатывают последовательно во встречном направлении с разворотом комплекса у границ выемочного пол ца 18О . Указанным полосам при их отработке , придают встречный уклон, равный 1 0,5-&, где f,- высота отрабатываем го сло , м; f - длина выемочного пол .м. Благодар посто нному уклону движени комплекса производ т непрерывную выемку слоев попространственной спирали с исключением монтажно-демонтажных работ . Одновременно с выемкой полезного ископаемого в каждой noiioce однЪго сло$ провод т конвейерный штрек 5, который дл смежной полосы смежного сло будет вентил ционным штреком.A powerful steep layer of minerals is divided into excavation fields 1, in which preparatory workings are carried out. The shas are worked out by layers of 2 libras in descending order with laying out the worked out space or roof collapsing, or in ascending order with laying the worked out npocfpatt-J. Each layer is divided into two strips 3, 4 in width the bands are equal to half the thickness of the reservoir. The strips within each layer are worked out successively in the opposite direction with a reversal of the complex near the borders of the excavation floor 18O. When they are mined, these bands are given a head bias equal to 1 0.5 - &, where f, is the height of the working layer, m; f - length of the notch floor. m. Due to the constant slope of the complex, continuous layers of the spatial spiral are removed, with the exception of installation and dismantling. Simultaneously with the excavation of the mineral in each noiioce of the single layer, a conveyor raft 5 is conducted, which for the adjacent strip of the adjacent layer will be a ventilation ram.
Данный способ разработки позвол ет значительно сократить монтажно-демонтажные работы и повысить интенсификацию ведени горных работ за счет исключени монтажно-демонтажных работ в процессе отработки слоев.This method of development allows to significantly reduce installation and dismantling works and increase the intensification of mining operations by eliminating installation and dismantling works in the process of mining layers.
