Description

В Основном авт. св. № 117234 описан взрывной снособ проходки скважин и выработок в горных породах с применением взрывобуров, состо щих из полой стальной трубы, метательной насадки и опоры.Basically auth. St. No. 117234 describes an explosive procedure for drilling wells and workings in rocks using explosion-drills consisting of a hollow steel pipe, a throwing nozzle and a support.

Этот известный способ имеет р д существенных недостатков: с возрастанием величины зар да примен емого взрывчатого вещества (ВВ) происходит увеличение размеров курков разрушаемой породы (шлама), что затрудн ет очистку забо  и вынос разбуренной породы; по известному способу взрывобурени  мало используютс  откольные  влени , св занные с работой горных пород на срез и изгиб, что, как известно,  вл етс  наиболее эффективны при разрушении; наконец, известный способ повышает стоимость бурени , так как наличие больших кусков шлама на забое требует специальных устройств дл  предохранени  инструмента (метательной насадки) от действи  взрывных волн.This known method has a number of significant drawbacks: with an increase in the magnitude of the charge of the explosive used (EX), there is an increase in the size of the hammer of the rock to be destroyed (sludge), which makes it difficult to clean the bottom and remove the drilled rock; according to the known method of explosive drilling, spalling phenomena associated with the work of rocks in shear and bending are little used, which, as is well known, is most effective in breaking; Finally, the known method increases the cost of drilling, since the presence of large pieces of sludge at the bottom requires special devices to protect the tool (throwing nozzle) from the action of blast waves.

Описываемый способ проходки скважин не имеет указанных недостатков и основан на принудительном рассеивании ампул с зар дами ВВ по поверхности забо  выработки, что достигаетс  введением ампул ВВ в забой по косым каналам вращающегос  бура, отсто щего от поверхности забо  на безопасном рассто нии.The described method of drilling does not have the indicated drawbacks and is based on the forced dispersion of ampoules with explosive charges over the production surface, which is achieved by introducing explosive ampoules into the bottom through oblique channels of a rotating drill that is at a safe distance.

На чертеже представлена схема ампульного взрывобура дл  осуществлени  описываемого способа.The drawing shows a diagram of an ampoule explosion drill for carrying out the described method.

Ампулы 1 с зар дами ВВ, подаваемые по колонне бурильных труб с помощью промывочной жидкости, воздуха или газа, поступают к взрывобуру и, проход  через отверсти  по косым каналам вращающейс  метательной насадки 2, рассеиваютс  в заданном пор дке и с большой скоростью по забою. При встрече с породой забо  они взрываютс .Ampoules 1 with explosive charges, supplied through a string of drill pipes by means of a flushing fluid, air or gas, reach the explosion drill and, passing through the openings through oblique channels of a rotating throwing nozzle 2, disperse in a predetermined order and with great speed down the face. When they encounter a slaughter breed, they explode.

Дл  сохранени  надлежащей дистанции насадки 2 от забо  и.слользуетс  опора 3, а дл  центрировани  взрывобура в скважине предусмотрен калибратор 4, который одновременно выполн.чет функции проработки скважины.To maintain the proper distance of the nozzle 2 from the bottom of the well, support 3 is used, and a calibrator 4 is provided for centering the blast hole in the well, which simultaneously performs a calculation of the well development function.

Описанный взрывобур предназначен дл  проходки глубоких и мелких скважин ,0рльших и малых диаметров (150 -т- 300 мм), а также другихThe described explosion drill is designed for drilling deep and shallow wells, with small and large diameters (150 - t - 300 mm), as well as other
