Embodiment 1

[0024] Example 1: A large-scale underground mine adopts the joint development of vertical shafts and slopes, and the sub-level caving method without pillars. The designed annual comprehensive production capacity of mining and dressing is 4 million tons. In order to maintain the continuous and stable mining production of the mine, there must be sufficient production preparations in the stope. For this reason, the mine needs to excavate 8000m of mining roadways every year (an average monthly excavation of about 670m). Boomer281 full-hydraulic drilling jumbo is used for tunneling and rock drilling, explosive charging jumbo or manual blasting is used for tunneling, and TORO301D diesel scraper is used for tunneling and slag removal. The labor organization adopts three shifts. When excavating the roadway, the centralized excavation production organization method with the area as the unit is adopted. There are four excavation teams, and each excavation team has three operation areas. ...

Embodiment 2

[0025]Example 2: A large-scale underground mine adopts the joint development of adit and slope road, and the sub-level caving method with bottom pillars for mining, and the designed annual comprehensive production capacity of mining and dressing is 1.5 million tons. In order to maintain the continuous and stable mining production of the mine, there must be sufficient production preparations in the stope. For this reason, the mine needs to excavate 4000m of mining roadway every year (an average monthly excavation of about 330m). Boomer281 full-hydraulic drilling jumbo is used for tunneling and rock drilling, explosive charging jumbo or manual blasting is used for tunneling, and TORO301D diesel scraper is used for tunneling and slag removal. The labor organization adopts three shifts. When excavating the roadway, the centralized excavation production organization method with the area as the unit is adopted, and the excavation team is divided into three groups: excavation rock dri...

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 out a 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 on a 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 invention relates to an underground mine excavation quasi-drilling roadway production organization method, in particular to a mining quasi-excavation production organization mode with multiple working face cycles, which is suitable for mines with sub-pillar caving method and sub-pillar no sub-caving method. 【Background technique】 [0002] The segmented caving method with pillars and the segmented caving method without pillars are commonly used mining methods in underground mines. The mines using this type of mining method have to excavate a large number of mining roadways every year. Therefore, the mining method is the main method of 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 mining required for mining 10,000 tons of ore in these mines varies greatly. Usually, mine excavation and excavation wor...
