Abstract
Изобретение относитс к горной промышленности и предназначено дл гидровскрышных работ. Цель - повышение эффективности разработки породе низкой водопроницаемостью за счет обеспечени возможности нарушени их целостности путем механического ослаблени при снижении энергозатрат на гидроразработку. С боковой стороны откоса уступа с опережением бур т скважину (СК) в месте образовани вруба (ВР) струей гидромонитора. Шаг проходки СК равен глубине ВР, обеспечивающего обрушение пород. Целик между СК удерживает породный массив. При образовании ВР целик уменьшаетс и разрушаетс , ускор процесс гидроразработки пород. 2 ил.The invention relates to the mining industry and is intended for hydrobearing. The goal is to increase the efficiency of rock development with low water permeability by providing the possibility of violating their integrity by mechanical weakening while reducing energy consumption for hydraulic development. On the side of the escarpment slope, ahead of time, a borehole (SC) is drilled at the site of formation of a cut-off (BP) with a jet of jetting machine. The pitch of the SC is equal to the depth of the BP, ensuring the collapse of rocks. The rear sight between the SC keeps the rock mass. With the formation of BP, the pillar is reduced and destroyed, accelerating the process of hydraulic development of rocks. 2 Il.
Description
Изобретение относитс к горной промышленности и может быть использовано при открытой разработке месторождений.The invention relates to the mining industry and can be used in open pit mining.
Цель изобретени - повышение эффективности разработки пород с низкой водопроницаемостью за счет обеспечени возможности нарушени их целостности путем механического ослаблени при снижении энергозатрат на гидроразработку.The purpose of the invention is to increase the efficiency of the development of rocks with low water permeability by providing the possibility of violating their integrity by mechanical weakening while reducing the energy consumption for hydraulic development.
На фиг.1 изображена схема размыва пород по данному способу; на фиг.2 - вид по А -А на фиг.1.Figure 1 shows the scouring of rocks in this method; figure 2 is a view along A-A in figure 1.
Способ осуществл етс следующим образом . С боковой стороны откоса уступа 1 с опережением бур т скважины 2. Их проход т в месте образовани вруба 3 струей 4 гидромонитора 5 с шагом между скважинами , равным глубине вруба 3, обеспечивающего обрушение пород уступа 1. Целик 6 между скважинами 2 удерживает породный массив и не разрушает скважины 2. При образовании вруба 3 ближний к нему целикThe method is carried out as follows. On the side of the slope of the ledge 1 ahead of the drilling of the well 2. They are held at the site of formation of a cut 3 with a jet 4 of the jetting machine 5 with a hole spacing equal to the depth of the cutting cut 3, ensuring the collapse of the rocks of the ledge 1. Target 6 between the wells 2 holds the rock mass and does not destroy wells 2. When a cut is formed, the pillar 3 nearest to it
6 уменьшаетс и разрушаетс ,ускор процесс обрушени надврубовой толщи пород. Сокращаютс врем образовани вруба и энергозатраты и,следовательно,повышаетс эффективность гидравлической разработки пород. Размытый грунт поступает в зумпф 7 и откачиваетс землесосом 8 по пульповоду 9 в гидроотвал. Оборотна вода подаетс по водоводу 10.6 is reduced and destroyed, accelerating the process of collapse of the above-pipe stratum of rocks. The cutting time and energy consumption are reduced and, consequently, the efficiency of hydraulic rock development increases. The eroded soil enters the sump 7 and is pumped out by suction pump 8 through the pulpway 9 to the hydraulic dump. Circulated water is supplied through conduit 10.
