Description

Technical Field

[0001] This invention belongs to the field of coal mine roadway excavation, specifically relating to a mining-excavation matching method based on rapid roadway excavation. Background Technology

[0002] Ordos Zhuanlongwan Coal Mine is a high-yield and high-efficiency mine with a designed working face length of over 5,000 meters and a mining width of over 300 meters, achieving a daily advance of 16 cuts (12.8 meters). To meet the demands of high production and efficiency, the fully mechanized mining face adopts a three-way roadway layout, including a haulage roadway, an auxiliary haulage roadway, and a return air roadway. Connecting roadways are also arranged between the haulage and auxiliary haulage roads, in addition to cut-outs, resulting in a large overall tunneling workload. However, tunneling is a preparatory step before coal mining; coal mining can only commence after tunneling is completed. Because tunneling requires prior exploration and subsequent roadway support, and the working space is limited, the efficiency of tunneling is far lower than that of coal mining. For every high-yield and high-efficiency mine, how to achieve efficient tunneling to match the demands of coal mining has always been a challenge. The applicant has explored related work and proposed two solutions, one of which is described in this invention. Summary of the Invention

[0003] To address the problem that existing tunneling operations are difficult to match with coal mining operations, this invention divides the tunneling operation into two stages: the first stage is the tunneling stage, and the second stage is the mining-tunneling matching stage. In the second stage, the auxiliary haulage roadway of the previous working face is used for exploration, and the haulage roadway and auxiliary haulage roadway are tunneled simultaneously, which can achieve the goal of a good mining-tunneling matching relationship in high-yield and high-efficiency mines.

[0004] Specifically, the present invention proposes a mining matching method based on rapid tunnel excavation, comprising the following steps:

[0005] Excavation stage: Arrange the main haulage roadway, auxiliary haulage roadway, and return air roadway;

[0006] The first working face is excavated, and the haulage roadway is excavated from the main haulage roadway. At the same time, the auxiliary haulage roadway is excavated from the main haulage roadway and the return air roadway is excavated from the return air roadway. A connecting roadway is arranged at certain intervals in the coal pillar section between the haulage roadway and the auxiliary haulage roadway.

[0007] The tunneling cut-out connects the sluice transport roadway and the return air roadway;

[0008] The auxiliary transport roadway of the previous working face is later used as the return air roadway of the next working face;

[0009] Mining and excavation matching stage: The first working face is used for fully mechanized coal mining, while the second working face is used for tunneling.

[0010] The tunneling work of the second working face includes advancing the tunneling work from the auxiliary haulage roadway of the first working face to the second working face to conduct exploration drilling to explore the range of the top and bottom plates of the coal seam in the second working face; tunneling the haulage roadway from the main haulage roadway along the bottom plate of the coal seam, and simultaneously tunneling the auxiliary haulage roadway from the return air roadway along the bottom plate of the coal seam, and arranging connecting roadways at certain intervals between the haulage roadway and the auxiliary haulage roadway.

[0011] After the haulage roadway and auxiliary haulage roadway are excavated to their positions, temporary windbreak devices are installed in all connecting roadways in the coal pillar of the second working face section. In the coal pillar of the section, auxiliary connecting roadways are excavated from the auxiliary haulage roadway to the haulage roadway. Then, the second working face cut-out is excavated from the haulage roadway toward the first working face. Temporary windbreak and support devices are installed in the middle of the cut-out to divide the cut-out into two parts along the width direction.

[0012] The auxiliary haulage roadway of the first working face is extended to connect with the return air roadway, and a temporary windbreak device is installed at the connection between the auxiliary haulage roadway and the return air roadway. The auxiliary haulage roadway of the first working face becomes the return air roadway of the second working face. The tunneling roadway connects the auxiliary haulage roadway of the second working face with the auxiliary haulage roadway, and a temporary windbreak device is installed at the connection between the auxiliary haulage roadway and the return air roadway.

[0013] The second working face is used as a reference for the first working face for mining operations, and the third working face is used as a reference for tunneling operations, and this cycle continues.

[0014] Preferably, the auxiliary haulage roadway of the first working face is connected to the auxiliary haulage main roadway when in use, and is connected to the return air roadway of the next working face when in use.

[0015] Preferably, the coal mined from the first working face is transported from the haulage roadway to the haulage main roadway. Fresh air enters the haulage roadway and the auxiliary haulage roadway from the haulage main roadway and the auxiliary haulage roadway, respectively. The fresh air in the auxiliary haulage roadway converges in the haulage roadway through the connecting roadway and then enters the coal mining area. After becoming exhaust air, it enters the return air roadway through the return air roadway. During the mining process of the first working face, only the connecting roadway closest to the coal mining area is opened.

[0016] Preferably, the coal excavated from the conveyor roadway is transported from its interior to the main conveyor roadway, and the coal excavated from the auxiliary conveyor roadway is transported to the main conveyor roadway via the connecting roadway and then via the conveyor roadway. Except for the connecting roadway closest to the excavation face, temporary windbreak devices are installed in the connecting roadway. Fresh air enters the conveyor roadway of the second working face from the main conveyor roadway, enters the auxiliary conveyor roadway of the second working face via the connecting roadway, and exhaust air returns to the return air roadway via the auxiliary conveyor roadway of the second working face.

[0017] Preferably, the coal extracted from the cut-out is transported from one side of its cross-section through the conveyor roadway of the second working face to the conveyor main roadway; fresh air flows from the conveyor main roadway into the conveyor roadway of the second working face, passes through one side of the cut-out cross-section and enters the cut-out excavation face, and exhaust air passes through the other side of the cut-out cross-section, the auxiliary connecting roadway, and the auxiliary conveyor roadway of the second working face back to the return air main roadway.

[0018] Preferably, the temporary windbreak and support device includes individual pillars spaced apart along the length of the cut and water-filled barriers between the individual pillars.

[0019] Preferably, when the third working face is being mined, the auxiliary haulage roadway of the second working face is used as the return air roadway of the third working face. A temporary windbreak device is arranged at the end where the auxiliary haulage roadway connects to the main auxiliary haulage roadway, and the auxiliary haulage roadway of the second working face becomes the return air roadway of the third working face.

[0020] The beneficial technical effects of this invention are as follows: The mining and tunneling matching of this invention is divided into two stages. In the first stage, only tunneling work is carried out, without coal mining. All workers are concentrated on tunneling to reduce the overall tunneling time in the first stage and achieve coal mining as soon as possible. The second stage is the mining and tunneling matching stage, where coal mining and tunneling work are carried out simultaneously. While mining one working face, tunneling work on the next working face is carried out simultaneously, and the auxiliary haulage roadway of the previous working face is used for the detection work of the next working face. In this stage, the haulage roadway and the auxiliary haulage roadway are tunneled synchronously, and the auxiliary haulage roadway is connected to the return airway during tunneling. Combined with the connecting roadway, it is beneficial for coal output and ventilation when the haulage roadway and the auxiliary haulage roadway are tunneled synchronously. When tunneling the cut, the haulage roadway and the auxiliary haulage roadway of this working face are used in combination with temporary windbreaks and support devices to facilitate coal output and ventilation of the cut. This invention can achieve the goal of good mining and tunneling matching relationship in high-yield and high-efficiency mines. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-6 Specific embodiments of the present invention will be described in detail below.

[0032] To address the problem of existing tunneling operations being difficult to match with coal mining operations, this invention, without altering the original three-way roadway layout (including a haulage roadway, an auxiliary haulage roadway, and a return air roadway, with connecting roadways between the haulage and auxiliary haulage roads, and additional cut-in sections), divides the tunneling operation into two stages: the first stage is the tunneling stage, and the second stage is the mining-tunneling matching stage. In the second stage, the auxiliary haulage roadway from the previous working face is used for exploration, while the haulage and auxiliary haulage roads are simultaneously tunneled, achieving a good mining-tunneling matching relationship in high-yield and high-efficiency mines. Specifically, combined with... Figure 1-6 The present invention will be described in detail in the following two embodiments.

[0033] Example 1

[0034] A mining matching method based on rapid tunnel excavation includes the following steps:

[0035] Tunneling stage: such as Figure 1 As shown, the main conveyor roadway 01, the auxiliary conveyor roadway 02, and the return air roadway 03 are arranged, and the spacing between the main conveyor roadway 01, the auxiliary conveyor roadway 02, and the return air roadway 03 is set according to maintenance requirements.

[0036] The first working face 10 is being excavated, and is the first mining face. It includes the excavation of the haulage roadway 11 from the main haulage roadway 01, the excavation of the auxiliary haulage roadway 12 from the auxiliary haulage roadway 02, and the excavation of the return air roadway 13 from the return air roadway 03. The haulage roadway 11, the auxiliary haulage roadway 12, and the return air roadway 13 are excavated simultaneously. The haulage roadway 11, the auxiliary haulage roadway 12, and the return air roadway 13 are arranged in parallel. The section coal pillar 14 is located between the haulage roadway 11 and the auxiliary haulage roadway 12. A connecting roadway 14 is arranged at regular intervals between the haulage roadway 11 and the auxiliary haulage roadway 12. After the haulage roadway 11, the auxiliary haulage roadway 12, and the return air roadway 13 are excavated to the designed position, the excavation cut-out 16 connects the haulage roadway 11 and the return air roadway 13. The coal mining area of ​​the first working face 10 is formed between the haulage roadway 11 and the return air roadway 13.

[0037] The auxiliary haulage roadway 12 of the first working face will later be used as the return air roadway 23 of the next working face, namely the second working face 20. That is, the auxiliary haulage roadway of the previous working face will later be used as the return air roadway of the next working face. The connection method between the auxiliary haulage roadway 12 of the first working face and the auxiliary haulage main roadway 02 in the initial stage is described in [reference needed]. Figure 4 (a); When it is later used as the return air roadway 23 of the second working face 20, the connection method with the return air main roadway 03 is as follows. Figure 4 (b) At this time, a temporary windbreak device 27 is installed at the connection between the auxiliary haulage roadway 12 and the auxiliary haulage main roadway 02.

[0038] In the first stage of this invention, only tunneling work is carried out, without coal mining. All workers are concentrated on tunneling work to reduce the overall tunneling time in the first stage and to achieve coal mining as soon as possible.

[0039] Mining and matching stage: such as Figure 2-3 As shown, the first working face 10 is subjected to integrated mechanized coal mining, while the second working face 20 is being excavated. The coal mined from the first working face 10 is transported from the conveyor roadway 11 to the conveyor main roadway 01. Fresh air enters the conveyor roadway 11 and the auxiliary roadway 12 from the conveyor main roadway 01 and the auxiliary roadway 02, respectively. The fresh air in the auxiliary roadway 12 is connected to the conveyor roadway 11 via the connecting roadway 15 and then enters the coal mining area. After becoming exhaust air, it enters the return air roadway 03 via the return air roadway 13. During the mining process of the first working face 10, only the connecting roadway 15 closest to the coal mining area is opened, and the other connecting roadways 15 are temporarily closed by temporary windbreak devices 17. Since the focus of this invention is on excavation, other coal mining details of the first working face 10 will not be described here.

[0040] like Figure 2-3 As shown, the exploration borehole 29 is constructed from the auxiliary haulage roadway 12 of the first working face 10 to the advanced tunneling face (the haulage roadway 21 and auxiliary haulage roadway 22 of the second working face) to explore the top and bottom plate range of the coal seam of the second working face 20 (the development of coal seam undulation).

[0041] like Figure 2 , Figure 5 As shown in (a), the second working face 20 is the working face following the first working face 10. The tunneling work of the second working face includes tunneling the haulage roadway 21 from the main haulage roadway 01 along the coal seam floor, and simultaneously tunneling the auxiliary haulage roadway 22 from the return air roadway 03 along the coal seam floor. The haulage roadway 21, the auxiliary haulage roadway 22, and the return air roadway 23 are arranged in parallel. A section coal pillar 34 is formed between the haulage roadway 31 and the auxiliary haulage roadway 32. A connecting roadway 34 is arranged at certain intervals between the haulage roadway 31 and the auxiliary haulage roadway 32. The coal mining area of ​​the second working face 20 is formed between the haulage roadway 21 and the return air roadway 23.

[0042] Coal excavated from the haulage roadway 21 is transported from its interior to the haulage main roadway 01. Coal excavated from the auxiliary haulage roadway 22 is transported through the connecting roadway 25 and then through the haulage roadway 21 to the haulage main roadway 01. Except for the connecting roadway 25 closest to the excavation face, that is, except for the connecting roadway 25 furthest from the main roadway, a temporary windbreak device 27 is installed in the connecting roadway 25. Fresh air enters the haulage roadway 21 of the second working face from the haulage main roadway 01, passes through the connecting roadway 25 and enters the auxiliary haulage roadway 32 of the second working face. Exhaust air returns to the return air main roadway 03 through the auxiliary haulage roadway 32 of the second working face.

[0043] like Figure 3 As shown, after the haulage roadway 21 and auxiliary haulage roadway 22 are excavated to their positions, temporary windbreak devices 27 are arranged in all connecting roadways 25 in the coal pillar of the second working face section; auxiliary connecting roadways 251 are excavated from the auxiliary haulage roadway 22 to the haulage roadway 21 in the coal pillar 24 section; then the second working face cut-hole 26 is excavated from the haulage roadway 21 towards the first working face 10; a temporary windbreak and support device 28 is arranged in the middle of the cut-hole 26. The temporary windbreak and support device 28 includes individual support pillars Z5 arranged at intervals along the length of the cut-hole 26 and water-filled barriers between the individual support pillars Z5. The temporary windbreak and support device 28 can divide the cut-hole 26 into two parts along the width direction. The temporary windbreak and support device 28 lags behind the excavation face of the cut-hole 26 by a certain distance.

[0044] The coal extracted from eye 26 comes from one side of its cross-section ( Figure 3 The middle section is on the left side. The rubber transport roadway 21 of the second working face is transported to the rubber transport main roadway 01. Fresh air enters the rubber transport roadway 21 of the second working face from the rubber transport main roadway 01, passes through one side of the cut-out section and enters the cut-out excavation face. Exhaust air passes through the other side of the cut-out section, the auxiliary connecting roadway 28, and the auxiliary transport roadway 22 of the second working face and returns to the return air main roadway 03.

[0045] The auxiliary transport roadway 12 of the first working face will be used as the return air roadway 23 of the second working face 20, such as Figure 4As shown in (b), the auxiliary haulage roadway 12 of the first working face is extended to connect with the return air roadway 03, and a temporary windbreak device 27 is arranged at the connection between the auxiliary haulage roadway 12 and the auxiliary haulage roadway 02, so that the auxiliary haulage roadway 12 of the first working face becomes the return air roadway 23 of the second working face 20; Figure 5 As shown in (b), the tunneling roadway connects the second working face auxiliary haulage roadway 22 with the auxiliary haulage main roadway 02, and a temporary windbreak device 27 is arranged at the connection between the auxiliary haulage roadway 22 and the return air main roadway 03.

[0046] The second working face is mined using the first working face as a reference, while the third working face is excavated using the second working face as a reference, and this cycle continues; when mining the third working face, if... Figure 5 As shown in (c), the auxiliary transport roadway 22 of the second working face is used as the return air roadway of the third working face. A temporary windbreak device 27 is arranged at the end of the auxiliary transport roadway 22 that connects to the auxiliary transport main roadway 02, and the auxiliary transport roadway 22 of the second working face becomes the return air roadway of the third working face.

[0047] In the second stage, the mining and tunneling balance stage begins, with coal mining and tunneling proceeding simultaneously. While one working face is being mined, the next working face is being tunneled simultaneously, and the auxiliary haulage roadway of the previous working face is used for exploration of the next working face. In this stage, the haulage roadway and the auxiliary haulage roadway are tunneled synchronously, and the auxiliary haulage roadway is connected to the return airway during tunneling. The connecting roadway facilitates coal extraction and ventilation during the synchronous tunneling of the haulage roadway and the auxiliary haulage roadway. When tunneling the cut, the haulage roadway and the auxiliary haulage roadway of this working face are used, along with the temporary windbreak and support device 28 (removed during the second working face mining), to facilitate coal extraction and ventilation of the cut.

[0054] The subsequent working face cut-out 36 adopts a rectangular roadway cross-section with dimensions of 9.4 × 3.6 m. It employs a comprehensive support system combining anchor mesh, anchor cables, anchor cables, and steel strips, using individual props. Specifically, as follows... Figure 6 As shown, within the cut-in 26, a metal mesh Z1 is laid along the coal wall and roof of the cut-in 26. Then, anchor bolts Z4 are used to reinforce the coal wall, and anchor cables Z3 are used to reinforce the roof. The anchor cables in the same row are connected as a whole by a steel strip Z2. A temporary windbreak and support device 28 is arranged in the middle of the cut-in 26. The temporary windbreak and support device 28 includes individual support columns Z5 arranged at intervals along the length of the cut-in 26 and water-filled barriers between the individual support columns Z5.
