Abstract

Изобретение относитс к горной промышленности. Целью изобретени вл етс снижение затрат на проведение и поддержание выработок (В) при разработке сближенных пластов (П) . Первоначально отрабатывают надрабатывающий П спаренными лавами (Л) 9 и 10 к границам выемочного участка. Одновременно по надрабатываемому П под выработанным пространством провод т участковые В 1, 2 и 3 и полевые В 4. Полевые В 4 провод т под углом, превышающим на 10-20° угол между плоскостью, раздел ющей зоны с повышенными и пониженными напр жени ми, и плоскостью, перпендикул рной к напластованию и проход щей через краевую часть надрабатывающего П. Посредством В 4 соедин ют В 1, 2 и 3 с вспомогательными В 5-7. После отработки Л 9 и 10 и проведени В 1, 2 и 3 на всю длину выемочного участка вынимают надрабатываемый П в направлении, противоположном движению Л 9 и 10. Отработку Л надрабатываемого П ведут с отставанием на ширину выемочного участка от краевой части надрабатывающего П. Разработка пластов может быть осуществлена одиночными Л. 1 з. п. ф-лы, 3 ил.The invention relates to the mining industry. The aim of the invention is to reduce the cost of conducting and maintaining workings (B) in the development of adjacent layers (P). Initially, the overworking is worked out with paired lavas (L) 9 and 10 to the borders of the excavation site. At the same time, precinct B 1, 2 and 3 and field B 4 are conducted over the worked P under the developed space. The field B 4 is held at an angle exceeding by 10-20 ° the angle between the plane separating the zones with high and low voltages and by a plane perpendicular to the stratification and passing through the marginal part of working on P. By means of B 4, B 1, 2 and 3 are connected with auxiliary B 5-7. After working out L 9 and 10 and carrying B 1, 2 and 3 for the entire length of the excavation section, the overworked P is taken out in the direction opposite to the movement of 9 9 and 10. The working of the L overworked P is delayed by the width of the excavation site from the edge part of the overworking P. layers can be carried out by single L. 1 h. n. f-ly, 3 ill.

Claims

Claim

1. A method of developing strata of minerals at great depths ₍ including mining the lavas of the producing layer in the direction of the boundaries of the excavation section, simultaneous conducting of the mine workings under the worked-out space of the mining layer and field workings between the auxiliary workings of the producing layer and local workings, the location of the field workings at an angle to a plane perpendicular to the formation and passing through the edge part of the overburden, formation under the working space of zones with increased and reduced voltages, characterized in that, in order to reduce the cost of conducting and maintaining mining operations in the development of adjacent formations, the local workings are carried out along the work ;, 'formation, and the field workings pass at an angle exceeding by 10-20 the angle between the plane dividing the zones with increased and reduced stresses, and the plane perpendicular to the formation and passing through the edge part of the mining layer, then after mining the lava of formation and of local workings fulfill nad3 ops lava formation in the opposite direction.

2о The method according to claim 1, characterized in that the lava mining of the produced layer is lagging behind the width of the excavation section from the edge part of the working layer, 'of the formation.
