Embodiment 1

[0024] Example 1: A large-scale underground mine adopts joint development of shafts and ramps, non-pillar sublevel caving mining, and has a designed annual production capacity of 4 million tons. In order to maintain the mine's continuous and stable mining production, there must be sufficient production reserves in the stope. For this reason, the mine needs to excavate 8000m of mining roadways every year (an average of about 670m per month). For roadway boring, Boomer281 full-hydraulic rock drilling rig is used for boring and rock drilling, charging pallet or manual blasting and blasting, TORO301D diesel scraper is used for digging and slagging, and the labor organization uses three-shift manufacturing. When driving the roadway, it adopts the centralized driving production organization method with the area as the unit. There are four driving teams, each of which has three operation areas. Divide the working roadway into three areas (numbered as: 1#, 2#, 3#). In each area, there ...

Embodiment 2

[0025] Example 2: A large-scale underground mine adopts flat tunnels and ramps to jointly develop, and sub-pillar sublevel caving mining, with a designed comprehensive production capacity of 1.5 million tons per year. In order to maintain continuous and stable mining production in the mine, there must be sufficient production reserves in the stope. For this reason, the mine needs to excavate 4,000m of mining roadways every year (average of about 330m per month). For roadway boring, Boomer281 full-hydraulic rock drilling rig is used for boring and rock drilling, charging pallet or manual blasting and blasting, TORO301D diesel scraper is used for digging and slagging, and the labor organization uses three-shift manufacturing. When driving the roadway, the centralized driving production organization method with the area as the unit is adopted, and the driving team is divided into three groups: driving rock drilling, driving charge blasting, and driving slag discharge, and undertake...

Abstract

The invention relates to a production organization method for a development driving tunnel of an underground mine. The method comprises the following steps: dividing an operation tunnel into a plurality of production areas, performing a production operation of the same process in each area, intensively carrying out a driving rock drilling operation in one production area, intensively carrying outa driving charge blasting operation in one production area, and intensively carrying out a driving slag discharge operation in one production area so as to form a circulating unit for carrying out a development driving operation of the mine. The method has the advantages that when the development driving performs a production process operation in one area, because a plurality of tunnels to be operated are in the area, the operating personnel in a group can take some time off for auxiliary operations of jacking and prizing tunnel pumice stones, clearing bottom plate obstacles, clearing slag ona heading face and the like in the tunnels; therefore, the auxiliary operation time is shortened, and the efficiency of the equipment is improved.

Description

【Technical Field】 [0001] The present invention relates to a production organization method for underground mine excavation tunnels, in particular to a production organization method for excavation excavation with multi-working surface circulation, which is suitable for sub-column sublevel caving method and non-column sublevel caving method mines. 【Background technique】 [0002] Sub-pillar sublevel caving and sub-pillar sublevel caving are commonly used mining methods in underground mines. Mines using this type of mining method have to excavate a large number of mining roadways every year. Therefore, mining is the main reason for underground mines. Process flow. According to the occurrence conditions of the ore body, the production scale of the mine, the mining method and its parameters used in the production, the amount of prospective roadway required for mining 10,000 tons of ore varies greatly in these mines. Normally, mine excavation and excavation work consists of several ma...
