Abstract
The utility model relates to a roadway roof protective net of a coal face. A roadway cross section filling mode is complex and enables construction to be inconvenient, and roof guniting material and roadway filling material are prone to being mixed into working face coal flows and affecting coal quality. In order to solve the technical problems, the roadway top protective net of the coal face comprises multiple parallel steel wire ropes and a metal net. Fixing anchor rods are arranged at the two ends and the middle section of each steel wire rope and fix the steel wire ropes to a roadway roof in parallel. The metal net is arranged on the steel wire ropes in a laying mode. According to the roadway roof protective net device of the coal face, the mode of constructing the fake roof is adopted for replacing the filling scheme, consumed material is simple and low in cost, workloads are small, and construction operation is facilitated. The roadway roof protective net of the coal face is easy to construct, safe and reliable, ensures the coal quality and is widely suitable for a coal mine and other environments needing roadway protection.
Description
Technical field
The utility model relates to a kind of coal-face protector, particularly top, a kind of coal-face lane protecting net device.
Background technology
While crossing old working back production, owing to being subject to mining pressure impact, need in advance tunnel to be processed, guarantee that exploitation process roof timbering is effective.According to influence degree, generally take the mode of drift section filling to prevent from crushing.Drift section filling method, method is complicated, construction inconvenience, and also top board Grouting, tunnel filling material are easily sneaked into work plane coal stream and are affected ature of coal.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, and top, a kind of coal-face lane protecting net device is provided.
For solving the problems of the technologies described above, top, this coal-face lane protecting net device, comprise many parallel wire rope and wire lath, wherein every wire rope two ends and stage casing are equipped with fixing anchor bar, above-mentioned fixing anchor bar is fixed on back wire rope is parallel, and described wire lath is just laid on wire rope.
So design, top, the utility model coal-face lane protecting net device, rely on old working top board as the fixed point of taking root, in advance at top board construction wire rope fixing anchor bar, after old wire rope is fixing by fixing anchor bar, along roadway direction, lay, above wire rope, lay wire lath, form false top reliably.Among coal-winning machine coal cutting process, the false jacking of tunnel wire rope, wire lath enters set cap rear, and leading pressure or occur roof cracking, fall cash situation is all stopped by flexible false top, is convenient to force piece and passes forward.Compare with stope filling and support tunnel, utilize fraud top mode to replace charging formula, selected material is relatively simple, cost is low, and workload is little simultaneously, is more conducive to construction operation.
As optimization, described wire lath is Double-level Reticulated, and its mesh assumes diamond in shape.So design, old wire rope complexed metal rhombus net design, environmental protection and reducing costs.
As optimization, the spacing between described wire rope is 0.6m-0.8m.So design, according to span length, is evenly distributed wire rope, has effectively played support action.
As optimization, described wire lath and tunnel are with wide.So design wire lath tiles above wire rope, by wire rope, is fixed, and metal rhombus net lays width ensuring coverage tunnel, has effectively played protective action.
Top, the utility model coal-face lane protecting net device, construction is simple, more safe and reliable, has guaranteed ature of coal, and extensively applicable colliery etc. needs in the protective environment of tunnel.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, top, this coal-face lane protecting net device is described further:
Fig. 1 is the longitudinal profile structural representation of top, this coal-face lane protecting net device;
Fig. 2 is the horizontal section structural representation of top, this coal-face lane protecting net device;
Fig. 3 is that structural representation is looked up in the part of top, this coal-face lane protecting net device.
In figure: 1 is fixing anchor bar, 2 is wire rope, and 3 is wire lath, 4 backs, and 5 is coal-winning machine coal cutting top board line.
The specific embodiment
Embodiment one: as shown in Figure 1, top, this coal-face lane protecting net device comprises many parallel wire rope 2 and wire lath 3, wherein every wire rope 2 two ends and stage casing are equipped with fixing anchor bar 1, above-mentioned fixing anchor bar 1 is fixed on back 4 wire rope 2 is parallel, and described wire lath 3 is just laid on wire rope 2.Described wire lath 3 is Double-level Reticulated, and its mesh assumes diamond in shape.Spacing between described wire rope 2 is 0.6m-0.8m.Wire lath 3, all covers on back 4 with wide with tunnel.The height of wire rope 2 in tunnel is greater than the height of working surface coal mining machine coal cutting top board line 5, and wire rope 2 is stretching.
Claims (4)
1. top, coal-face lane protecting net device, it is characterized in that: comprise many parallel wire rope and wire lath, wherein every wire rope two ends and stage casing are equipped with fixing anchor bar, and above-mentioned fixing anchor bar is fixed on back wire rope is parallel, and described wire lath is just laid on wire rope.
2. top, coal-face according to claim 1 lane protecting net device, is characterized in that: described wire lath is Double-level Reticulated, and its mesh assumes diamond in shape.
3. top, coal-face according to claim 2 lane protecting net device, is characterized in that: the spacing between described wire rope is 0.6m-0.8m.
