Description

3. Отработку запасов этого блока осуществл ют одновременно от центра расход щимис фронтами по падению 4 и восстанию 5 с выдачей полезного, ископаемого через один из центрально;отнёс нных стволов 3.3. The development of reserves of this block is carried out simultaneously from the center with diverging fronts along the fall of 4 and the uprising of 5 with the delivery of minerals through one of the central, related trunks 3.

После этого, как фронты 4 и 5 очистных работ достигли границ б и 7 проектного контура охранного целика (без учета ширины бермы безопасности) и произошла разгрузка от горного давлени подработанного массива, приступают к сооружению главных стволов 2. Таким образом, имеет место технологическое совмещение очистных работ и работ по сооружению главных стволов, Когда фронты очистных работ вышли за пределы границ проектного контура охранного целика и произошла разгрузка массива от горного давлени , приступают к строительству подшахтных зданий у главных стволов.After that, as fronts 4 and 5 of the treatment works reached the borders of b and 7 of the design contour of the guard pillar (without taking into account the width of the security berm) and unloading of the worked-out massif from the mountain pressure, the construction of the main shafts 2 begins. Thus, the technological combination of the treatment works and works on the construction of the main shafts, When the front of the sewage treatment works went beyond the boundaries of the design contour of the guard pillar and the mass was unloaded from the mountain pressure, they began the construction of shaft buildings th at the main trunks.

Таким образом, по сравнению с прототипом предложенный способ позвол ет за счет технологического совмещени очистных работ и работ по сооружению главных стволов значительно сократить сроки строительства шахты и снизить потери угл в недрах.Thus, in comparison with the prototype, the proposed method allows, due to the technological combination of treatment and construction of the main shafts, to significantly reduce the construction time of the mine and reduce coal losses in the bowels.

the opening of this block by centrally assigned blocks and central main vertical shafts and the priority development of its reserves, characterized in that, in order to accelerate the commissioning of the mines of the primary niy6okoro mine while reducing losses of minerals in the security pillars of the main shafts due to the technological combination of work for the extraction of reserves and the construction of these shafts, the mine field is divided into different-sized blocks along strike, with the size of the pioneer block along strike equal to the size of the guard pillar at the main trunks, and in the fall the size of the indicated block is taken equal to the size of the horizon, but not less than the size of the guard pillar at the main trunks, the development of the pioneer block reserves is carried out simultaneously by diverging fronts from the center along the fall and uprising with the supply of minerals through one of the centrally related shafts, and the construction of the main vertical shafts is started after unloading from the rock pressure of the massif adjacent to the design contour of the guard pillar under ihtnye building in these trunks excluding safety berm width.
