Description

Изобретение относитс к горной промышленности и может быть ис пользовано дл отработки крутопадающих месторождений с твердеющей закладкой.The invention relates to the mining industry and can be used for mining steeply dipping deposits with a hardening bed.

Известен способ отработки крутопадающих месторождений с закладкой выработанного пространства при камерно-целиковой системе разработки {.There is a method of mining steeply dipping deposits with the laying of the goaf with the chamber-based development system {.

Недостатком известногр способа вл етс недостаточна несуща способность рудных целиков на больших глубинах, значительные потери руды и низка безопасность ведени горных работ.The disadvantage of the known method is the insufficient carrying capacity of the ore pillars at great depths, significant loss of ore and low safety of mining operations.

Известен также Способ разработки крутопадающих рудных месторождений, включающий сплошную выемку руды сло ми, взрывоотбойку руды, выпуск ее и закладку выработанного нространства твердеющей смесью 2.A method of developing steeply dipping ore deposits is also known, including a continuous excavation of the ore with layers, ore blasting, its release and the laying of the developed area with a hardening mixture 2.

Недостатком данного.способа вл етс сравнительно низка скорость отработки месторождени .The disadvantage of this method is the relatively low rate of field development.

Целью насто щего изобретени вл етс интенсификаци очистной выемки.The purpose of the present invention is to intensify the clearing recess.

Поставленна цель достигаетс тем, что отработку сло ведут послраоватеЛьно вертикальными прирезками, после отбойки и выпуска руды из прирезки, ее закладывают и во врем твердени закладочного материала начинают отработку следующей прирезки с образовани компенсационного пространства в ней в виде вертикальной щели, причем компенсационное пространство располагают со стороны рудного массива длинной стороной параллельно заложенной прирезки , а затем отбивают прирезку веерами глубоких скважин последовательно от компенсационного пространства к заложенному выработанному пространству отработанной прирезки.The goal is achieved by the fact that the mining of the layer is carried out by vertical cuttings, after the cutting and release of ore from the cutting, it is laid and during the setting material hardening, the following cutting is started to form the compensation space in it in the form of a vertical slit, and the compensation space is placed on the side of the ore massif with the long side parallel to the pavement laid, and then they beat off the trimming with fans of deep wells sequentially from the compensation p a nd to the pledged goaf waste prirezki.

Сущность изобретени по сн етс чертежом .The invention is illustrated in the drawing.

На фиг. I изображен разрез рудной залежи (панели) по простиранию; на фиг. 2 -сечение рудной залежи (панели) горизонтальной плоскостью; на фиг. 3 - то же, HO вкрест простирани .FIG. I shows a section of the ore deposit (panel) along the strike; in fig. 2 - cross-section of the ore deposit (panel) by the horizontal plane; in fig. 3 - the same, HO across the strike.

Claims

Initially, the ore deposit is divided into panels, which in turn are divided into vertical cuts. The development of vertical cutting begins with the creation of a compensation space 2, which is located with the long side perpendicular to the direction of cutting of the cuttings. The compensation space is created in the form of a vertical slot, which borders on the embedding rocks of the lying and hanging sides. To the compensation space, with the help of fans of deep wells I beat off the ore massif 4 trimming. The trimming of ore is done by fans of wells 3, pieces of opbie are arranged in a plane parallel to the long side of the compensation space. Fans of wells are drilled from a drift 5, driven down by running gears 6 with a sublevel field drift 7. Broken ore is cut through the Luchki 8 into shchtrek 9 for loading, for example, with self-propelled equipment. After a complete rehearsal 1 has been worked out, the developed space is filled with a hardening mixture 10. During the hard bookmark 10, without waiting for it to set completely, they start working out the next retraction with the creation of a compensation space from the ore massif with the long side parallel to the laid down retraction, and then beat off the cutting by well fans in a succession from the compensation space to the pledged developed space of the spent trimming while combining the cleaning work with the time of the solid masonry. The use of this method will allow to intensify the cleaning work during the development of steeply dipping deposits {(due to the combination of bookmark hardening with cleaning work. Invention The method of developing steeply dipping ore deposits, including continuous ore mining, ore blasting, production and laying of the developed space with a hardening mixture, different the fact that, in order to intensify the clearing excavation, the layer is being worked out successively with vertical cut-outs, after breaking and The following trimming starts from the trimming, its laying-out, and during the hardening of the backfill material, forming a compensation space in it in the form of a vertical slit, the compensation space being placed on the ore massif with the long side parallel to the laid cutting, and then beating the trimming with deep fans wells sequentially from the compensation space to the pledged worked-out space waste waste.
