Изобретение относитс к горному делу и может быть использовано дл проходки выработок различного назначени , напри мер дл размещени гидротехнического оборудовани .The invention relates to mining and can be used for excavating workings for various purposes, for example for the placement of hydraulic equipment.
Цель изобретени - снижение трудоемкости работ и увеличение скорости проходки вертикальной выработки большого диаметозThe purpose of the invention is to reduce the complexity of work and increase the rate of penetration of the vertical production of large diameter
Способ проходки вертикальной выработки осуществл ют следующим образомThe method of penetration of the vertical development is carried out as follows
Шарошечным буровым инструментом выбуривают кольцевую выработку (траншею ) шириной, например, 500 мм. В средней части траншеи расположен керн. С помощью клинового механизма осуществл ют скол керна в его основании. Произдо д т герметизацию кольцевого усть выработки с помощью резиновых или металлических уплотнений. В выработку H .ixe уплотнений нагнетают, например тиксотропный раствор, давлены- которого превышает атмосферное на 20%. За разности давлений керн поднимаетс (всплывает). После всплыти на 3 м н д устьем выработки подачу жидкости прекращают, а выступающую часть керна разрабатывают, например разрушают взрь-вом и транспортируют в ov вал. Далее описанные выше операции по извлечению керна попгор к .An annular excavation (trench) with a width of, for example, 500 mm is drilled with a roller drilling tool. In the middle of the trench is the core. With the help of a wedge mechanism, core chips are made at its base. Seal the annular wellhead with rubber or metal seals. In the production of H. Ixe seals they inject, for example, a thixotropic solution, the pressure of which exceeds atmospheric by 20%. Over the pressure difference, the core rises (floats). After ascending at 3 mn d the outlet, the supply of liquid is stopped, and the protruding part of the core is developed, for example, destroyed by gating and transported to the ov shaft. The following operations described above for the extraction of core popgor to.
