Embodiment 1

[0039]A novel room-and-pillar mining method provided by the present invention comprises step 1: dividing the mining area along the ore body trend, and arranging several inter-pillars between the mining areas; The top and bottom pillars are set between the ore blocks in the general direction, and the mine room and room pillars are set in the ore block; Step 3: Set the air intake uphill and the return air uphill in the inter-columns, and the air intake uphill, the return air uphill and the mine Set up a mine room connection road between the houses; Step 4: Arrange a shaft at the junction of the top and bottom pillars and the inter-pillar near the return air up the mountain, which can be used by two adjacent ore blocks in the mining area; Step 5: In the mine block at the bottom of the mine Arrange the cutting level roadway in the middle to connect the mine connecting road between the air inlet and the upper mountain; Step 6: The ore blocks in the mining area are mined from top to ...

Embodiment 2

[0041] Such as figure 1 As shown, in a novel room-and-pillar mining method layout system provided by the embodiment of the present invention, the mining area is divided along the ore body trend, inter-pillars are set between the mining areas, and the vertical ore body trend in the mining area is divided into ore blocks, and the vertical ore body trend is Between the ore blocks, the top and bottom pillars are set, and the ore blocks are divided into mine rooms and room ore pillars. In the inter-column between the mining areas, the inlet wind uphill and the return wind uphill are arranged at intervals; between the inlet wind uphill and the mine at the bottom of the ore block, a mine room connection road is set, and the return wind uphill and the backwind uphill are arranged at intervals. There are 2 mine connecting roads between the mine houses, one of which is arranged between the return air uphill and the mine at the bottom of the ore block, and the other is arranged between t...

Abstract

The invention relates to the technical field of mining, in particular to a novel room-and-pillar mining method and an arrangement system. Mining areas are divided in the ore body trend, a plurality of pillars are arranged between the mining areas, ore blocks are divided in the mining areas in the direction perpendicular to the ore body trend, top and bottom columns are arranged between the ore blocks in the direction perpendicular to the ore body trend, ore rooms and a room pillar are arranged in the ore block, and an air inlet uphill and an air return uphill are arranged in the pillars at intervals. Compared with the prior art, the novel room-and-pillar mining method has the advantages that trackless equipment can pass through the air inlet uphill and the air return uphill, so that the automatic trackless equipment can be conveniently adopted for stoping; draw shafts are arranged at the junctions of the top and bottom columns and the middle columns and are close to the ore rooms, and the ore transportation distance is short; and the mining area shares the air inlet uphill, the air return uphill and the draw shafts, the number of the ore rooms connection ways is small as needed, and the mining and cutting work amount is small.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a novel room-and-pillar mining method and an arrangement system. Background technique [0002] The underground room-and-pillar mining method is an efficient open-field mining method, which is mainly used for the mining of horizontal and gently inclined medium-thick ore bodies, and is suitable for ore bodies and surrounding rocks with moderate or higher stability. There are two main layout forms of the existing room-and-pillar mining method: [0003] The first layout form: typical is the room-and-pillar method of Xikuangshan Antimony Mine (Editorial Committee of Mining Design Manual, Mining Design Manual (Volume 2), Beijing, China Architecture and Building Press, 1987, P1100), which belongs to Ordinary room and pillar mining method. The room-and-pillar mining method arranges mining areas (or panel areas) along the strike, inter-pillars are set between mining areas (the width of t...
