Abstract

Способ разработки месторождений полезных ископаемых в виде рудных тел, включающий деление рудных зон по глубине на подэтажи и этажи и отработки их сверху-вниз с обрушением вышележащего массива пород или закладкой выработанного пространства инородным раздробленным материалом с меньшей прочностью и устойчивостью массива пород, а также разработку рудных тел снизу-вверх с традиционной технологией дроблением руды в блоках массовым взрывом, нарушающим окружающий породный массив, отличающийся тем, что ведут разработку рудных тел снизу-вверх слоевым способом с ограниченной выемочной мощностью слоя шпуровым (скважинным) способом из буровых ортов с применением механизмов бурения и конвейерного транспортирования рудного материала, причем параметры отбиваемого слоя соответствуют приемной способности конвейеров, подающих материал в рудоспуск, а из него в транспортный подъемный сосуд (например, скип), и разработку ведут, начиная с висячего бока залежи, и постепенно отрабатывают слой за слоем в сторону лежачего бока залежи, а для сбора материала, сползающего с конвейерного става и при разработке промежуточных слоев между выемочными по высоте и дробимыми позже, внизу создают траншеи, из которых по течкам подают его на общий конвейер, и при небольшой высоте выемочного слоя потери и разубоживание руды снижаются в 5-10 раз (до 1,5-2% соответственно), и создается устойчивое выработанное пространство, которое в зависимости от мощности рудного тела может быть разделено на категории и использовано в народном хозяйстве и в военной сфере. A method of developing mineral deposits in the form of ore bodies, including dividing the ore zones in depth into sub-floors and floors and working them up and down with the collapse of the overlying rock mass or laying the worked out space with foreign fragmented material with less strength and stability of the rock mass, as well as the development of ore bottom-up bodies with traditional technology of crushing ore in blocks by a massive explosion disrupting the surrounding rock mass, characterized in that they are developing ore bodies from bottom to top x by a layered method with a limited extraction capacity of the layer using a drilling (borehole) method from drilling units using drilling and conveyor transportation of ore material, and the parameters of the striked layer correspond to the receiving ability of conveyors supplying the material to the ore pass and from it to the transport lifting vessel (for example, skip), and development is carried out starting from the hanging side of the deposit, and gradually work out layer by layer towards the lying side of the deposit, and to collect material sliding from the conveyor stand and during the development of intermediate layers between the excavation heights and crushed later, trenches are created below, from which they are fed through the chutes to a common conveyor, and with a small excavation layer height, ore losses and dilution are reduced by 5-10 times (up to 1.5-2 %, respectively), and a stable developed space is created, which, depending on the capacity of the ore body, can be divided into categories and used in the national economy and in the military sphere.
