Изобретение относитс к горной промышленности и может быть использовано при разработке мощных пологих угольных пластов преимущественно под охран емыми объектами.The invention relates to the mining industry and can be used in the development of thick flat coal seams, mainly under protected objects.

. Известен способ разработки мощных пологих пластов под охран е1Фши объектами , включающий выемку угл камерами с оставлением поддерживающих целиков 1.. There is a method of developing powerful flat layers under the protection of objects, including the extraction of coal by cameras, leaving supporting pillars 1.

Однако данный способ характеризуетс значительны 1й потер ми угл .However, this method is characterized by significant 1st coal loss.

Известен также способ разработки мощных пологих угольных пластов т|5ем наклонными сло ми, включаюйдай проведение подготовительных выработок: There is also a known method for developing thick flat coal seams with inclined layers, including the carrying out of preparatory workings:

дл каждого из слоев до начала от-7 for each of the layers before the start of-7

работки последних и выемку слоев 2.recent work and excavation of layers 2.

Целью изобретени вл етс повышение эффективности и безопасности ведени очистных работ под охран емыми объектами.The aim of the invention is to increase the efficiency and safety of the clean-up operations under protected objects.

Это достигаетс тем, что в первую очередь осуществл ют выемку верхнего сло тонкими щел ми в послёДовагёЛбности от кровли к почве верхнего сло , затем тонкими щел ми отрабатывают нижний слой в последователышС и от почвы пласта к кровле нйЖШГсзГ аШГ после чего на полйую мощность отра- This is achieved by firstly excavating the upper layer with thin slits in the aftermath of the top layer from the roof to the soil, then using the thin slits to work the bottom layer in the sequence and from the soil of the reservoir to the top of the hub, then the field

батывают средний слой с закладкой выработанного пространства, причем выработки среднего сло образуют путем , объедине.ни смежных выработок . верхнего и нижнего слоев при выемке, целиков угл между ними, а слои соответственно отрабатывают после окончани смещени кровли перед очистным забоем каждого последующего по очередности выемки сло .The middle layer is stitched with the laying of the worked-out space, and the middle layer workings are formed by uniting the adjacent workings. the upper and lower layers during excavation, the pillars of the coal between them, and the layers, respectively, are worked out after the completion of the displacement of the roof before clearing the bottom of each successive excavation layer.

На фиг, 1 представлена схема от-. работки верхнего сло ; на фиг.2 то же,нижнего сло ; на фиг. 3 - то же, среднего сло .Fig, 1 presents the scheme from-. upper layer processing; Fig.2 is the same, the bottom layer; in fig. 3 - the same, the middle layer.

Claims

The powerful flat. Coal seam is worked by three inclined layers with the development workings for each layer before the development of the latter. The development of the upper layer, depending on the thickness of the reservoir, is carried out either through the reservoir or with the notch of the roof rocks of the Development well; the lower layer is also conducted either through the reservoir or with the notch of the rock of the reservoir soil. First of all, using the thin-slit groove unit, the upper layer 1 is worked by thin slits. 2 in sequence from the top of the layers to the soil of the upper layer. Following the development of the upper layer, after the completion of the mixing of the roof rocks, proceed to the excavation of the lower layer 3 by thin slits 3 in the sequence from the soil to the bottom of the lower surface. After the end-of-the-end rocks, they start working immediately on the full capacity of the middle layer 5 with laying the developed space. The middle layer is formed by dredging the coal between the adjacent workings 7 of the upper layer and the workings of the 8 lower layer. The proposed method provides highly efficient extraction of powerful semi-coal seams under protected objects. . . The invention The method of development of gently flat coal seams in three inclined layers, including the carrying out of preparatory workings for each of the layers prior to the development of the latter and the excavation of the layers, so that rota and / / / . 1ZL1ZL

Figure 2 shows the effectiveness and safety of the clean-up work under protected objects, first of all carrying out the top layer of a thin slit in a sequence from the roof to the top layer of the soil, then the bottom layer is worked out in a sequence from the reservoir to the bottom of the layer Then, the middle layer is worked out at full capacity with the laying of the worked-out space, and the middle layer is formed by combining adjacent workings of the upper and lower layers when excavating the pillars from hl between them, and the layers, respectively, are worked out after the end of the displacement of the roof before cleaning face of each subsequent layer excavation.
