Problems solved by technology

[0004] Machine gun joint mining refers to the coal mining process that integrates automatic drilling, manual blasting and coal drop, and hydraulic support support. The existing problems are that the coal wall is not completely cleaned, and the coal blocks between the support and the conveyor are difficult to clean. Go to the coal wall to clean the coal, resulting in high labor intensity and a large amount of coal dust

Embodiment Construction

[0021] Below is the combined figure 1 The present invention will be further described with implementation examples.

[0022] The technical scheme of the present embodiment is carried out according to the following steps:

[0023] (1) Drilling work is carried out before blasting, and the intelligent drilling vehicle 3 drives to the designated working face position, and is controlled by the intelligent drilling vehicle 3 according to the pre-designed hole position, hole distance, hole depth, blasthole angle and blasthole length 4~ 6 mechanical arms realize accurate positioning of the hole forming position and quickly and automatically fine-tune the hole forming position. After positioning, the hydraulic drilling rig is used to drill to realize the automatic and rapid hole forming of the drill bit;

[0024] (2) The 4 robotic arms of the intelligent charging device are used to automatically position and charge the explosives with a diameter of Ф60, and the new KYFK-001 sealing ma...

Abstract

The invention relates to the technical field of coal mining, in particular to an intelligent burst coal mining method. An intelligent drill carriage is adopted for positioning and hole drilling. A mechanical arm of an intelligent mechanical charging device is adopted for automatic positioning and charging, automatic hole sealing is achieved, an explosive charge is ignited for bursting according to the hole size, position, depth, inclination angle and coal cracking sequence in the bursting method, the burst coal body cracks and is not thrown out, large loosened coal blocks are formed, the block coal rate reaches more than 30%, an automatic coal collection device is adopted for coal loading after the coal blocks are formed, and finally an intelligent dust suppression system capable of adjusting the dust collection strength according to the coal dust amount percent is adopted for suppressing dust. According to the technical scheme, the labor intensity is low, the coal mining and the block coal rate are high, the coal dust amount is low, and the requirement for effective and safe coal mining is met.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to an intelligent explosive coal mining method. Background technique [0002] Traditional coal mining methods are mainly realized by gun mining or comprehensive intelligent coal mining technology, and there are also new coal mining methods such as machine gun combined mining. Among them, blast mining is mainly a coal mining process of blasting coal falling, manual coal loading, conveyor coal transportation and single pillar support. This coal mining process has many disadvantages, such as high labor intensity, low safety factor, and low production efficiency. When the coal dust is large and easy to cause fire, the safety factor is low. [0003] The comprehensive intelligent coal mining technology is to achieve intelligent operation in the basic processes of coal mining face such as coal breaking, coal loading, coal transportation, support and roof management. This coal mining t...
