Construction method of anchor plate artificial prosthetic roadway

Abstract

The invention discloses a construction method of an anchor plate artificial prosthetic roadway. The construction method comprises the steps: 1, selecting a construction place and direction according to engineering requirements of an upper ore body, and determinng a space size according to the required service function of the later stage; 2, marking roadway lines on site according to the place, thedirection and the size, and drilling anchor rod holes in a top plate ore column and a bottom plate ore rock according to the marking lines at certain intervals, wherein the anchor rod holes are symmetric up and down, and are arranged on a same plumb line; 3, after the anchor rod holes are drilled, mounting anchor rods, wherein the anchor rods inserted into the top plate ore column and the bottomplate ore rock are connected in a steel bar suspension connection mode through binding steel bars to form the inner vertical ribs, and meanwhile, the inner vertical rib structure is on the same plumbline; and 4, short ribs with threads at the two ends are fixed through binding at equal intervals on the inner vertical ribs which are connected between the top plate ore column and the bottom plate ore rock. The construction method is simple in process, high in safety, short in construction period, low in cost and capable of saving engineering materials.

Description

technical field [0001] The invention relates to the technical field of underground mine mining engineering, and more specifically relates to an anchor plate artificial false lane construction method suitable for upward horizontal stratified mining. Background technique [0002] In the process of underground mining of metal mines, there are some objective factors that require the construction of artificial false lanes to adjust the underground mining system. It can be summarized into two aspects: on the one hand, due to the mining of ore rocks within the scope, a goaf is formed, and the original roadway is destroyed or completely disappeared, which makes it difficult to transport the ore mined in layers in the next step; on the other hand, due to the early mining The limitation of the roadway layout system leads to the construction of artificial false roads in some areas for production adjustment, so as to realize safe, stable and efficient mining in mines. Among the current...

Problems solved by technology

Among the current mining methods of various artificial false alley structures, the traditional artificial false alley structure types are mostly concrete pouring, brick concrete and concrete prefabricated parts erection, etc. The construction period is long, the cost is high, and the labor intensity is high. An important factor in the application of roadway structure, it is of great significance to seek a simple and feasible new technology for artificial roadway construction
