Abstract

A multifunctional underground roadway tunneling locomotive is provided with a locomotive with functions of walking, rock drilling, loading, transporting, bolt supporting and the like; a drill bit of a rock drilling part adopts a diamond drill bit; the drilling rate is dozen times of that of the prior art; especially the large-diameter diamond drilling machine of the drilling part can be used for drill a large hole in the middle of a working surface to serve as a blasting cut hole to create a free surface to the blasting cut hole, so that the deep blasting in a straight hole is achieved. The multifunctional underground roadway tunneling locomotive is a new idea of blasting the underground tunneled roadway at home and abroad. The deep blasting of the straight hole enables the blasting force to explosives to be completely released in the blasting cut hole in the rock surface of the working surface, the blasting impact wave to the roadway is small, the rock crushing rate is high, the loading and transporting are facilitated, the usage rate of the blasting hole and the explosives are improved, and the comprehensive cost of the coal mine underground tunneled roadway construction is lowered. The multifunctional underground roadway tunneling locomotive is reasonable in design and structure, convenient to operate, and a brand-new replacing product of the coal mine underground tunneled roadway construction equipment, and suitable for exploitation of metallurgical ore in a tunnel.

Description

Technical field [0001] The invention relates to mechanized equipment for tunnel construction in underground coal mines. Background technique [0002] At present, domestic and foreign coal mine tunneling tunnel construction equipment is widely used manually operated ordinary pneumatic rock drills and inclined hole cutting methods for blasting. Due to the slow drilling speed and difficulty in ensuring the angle of the blasting hole, the amount of gunpowder is large and the blasting hole utilization rate is low , High cost, slow progress, and inability to achieve medium-depth blasting. Although the existing crawler rock drill with mechanized equipment can guarantee the angle of the blast hole and the speed of drilling the blast hole is also much higher, the method of blasting is still oblique hole cutting, and medium-depth blasting cannot be achieved. Moreover, when blasting is to be carried out, the rock drill must be driven out of the roadway, and the crawler rock drill is very s...
