1. Способ подготовки очистного блока для его отработки с разделением на два подэтажа при отработке крутопадающих, вытянутых по простиранию рудных залежей с богатым содержанием урана, выемкой руды горизонтальными слоями и применением твердеющей закладки, включающий проведение индивидуальных откаточных и вентиляционных ортов на откаточном и вентиляционном горизонтах, рудоспусков, вентиляционно-ходовых и материальных восстающих для каждого подэтажа, отличающийся тем, что индивидуальные откаточные и вентиляционные орты для подэтажей на откаточном и вентиляционном горизонтах располагают с максимальным приближением друг к другу посередине блока, причем ширину рудного (породного) целика между сближение располагаемыми ортами на откаточном и вентиляционном горизонтах в очистном блоке определяют из выражения1. The method of preparation of the treatment unit for its development with the division into two sub-floors during the development of steeply falling, elongated along the strike ore deposits with a rich uranium content, excavation of the ore in horizontal layers and the use of a hardening bookmark, including carrying out individual recoil and ventilation units at the outlet and ventilation horizons, ore pass, ventilation and material uprising for each sub-floor, characterized in that the individual retreat and ventilation unit for sub-floors n haulage and ventilation horizons with a maximum approach to each other in the middle block, wherein the width of the ore (rock) is entirely disposable convergence between the unit vectors in the haulage and ventilation horizons in the purification unit is determined from the expression Вцел≥[2·(а+D)+Внар.выр+bцел], м,For purposes ≥ [2 · (a + D) + B + b purposes nar.vyr] m, где Вцел - ширина целика между сближенно располагаемыми ортами на откаточном и вентиляционном горизонтах, м;where Int is the width of the pillar between closely spaced orts on the recoil and ventilation horizons, m; 2 - коэффициент, учитывающий схему расположения полевых рудоспусков и восстающих между ортами на откаточном и вентиляционном горизонтах;2 - coefficient taking into account the layout of field ore passages and uprising between orts on the return and ventilation horizons; а - расстояние от стенки откаточного орта до ближайшей стенки рудоспуска или восстающего, м;a - the distance from the wall of the recoil unit unit to the nearest wall of the ore or rising, m; D - диаметр рудоспуска, пройденного буровым комбайном, м;D is the diameter of the ore pass passed by the drill, m; Внар.выр - ширина нарезной выработки, м;In nar.vyr - the width of the rifled excavation, m; bцел - размер породного целика между рудоспуском одного подэтажа и слоевым ортом другого подэтажа, обеспечивающий устойчивое состояние выработок, м.b int - the size of the rock pillar between the ore pass of one sub-floor and the layered unit of another sub-floor, ensuring a stable state of the workings, m 2. Способ по п.1, отличающийся тем, что рудоспуски, вентиляционно-ходовые и материальные восстающие проводят комбайновым бурением полевыми на всю высоту этажа для каждого подэтажа.2. The method according to claim 1, characterized in that the ore passes, ventilation and material uprising are carried out by combine field drilling to the entire floor height for each sub-floor. 3. Способ по п.1, отличающийся тем, что материальные восстающие подэтажей на откаточном и вентиляционном горизонтах сбивают между собой выработками, в которых размещают материальный склад емкостью, обеспечивающей суточную потребность очистного блока в материалах.3. The method according to claim 1, characterized in that the material uprising subfloors on the discharge and ventilation horizons are knocked together by workings in which a material warehouse is placed with a capacity that ensures the daily need of the treatment unit for materials.
