Drilling, punching, screening and transporting integrated gas treatment method

Abstract

The invention belongs to the field of coal mining, and particularly relates to a drilling, punching, screening and transporting integrated gas treatment method. The drilling, punching, screening and transporting integrated gas treatment method comprises the steps of optimization of a high-pressure hydraulic power punching pump station, optimization of a crawler-type hydraulic drilling machine, optimization of a hydraulic puncher, optimization of a blowout control hole and a coal water collecting device and optimization of a crawler-type coal-water separating device. After the new procedures are carried out, the trouble that coal water generated by punching flows disorderly and coal-water separation is hard is solved thoroughly, and more importantly, single-hole metering can be achieved, the amount of coal punched out of one hole by a worker in one shift and the number of settled wage are clear at a glance, and the enthusiasm of the worker for hydraulic punching is greatly improved. Manual coal clearing, coal loading, coal transporting and other links are reduced, the coal water generated by punching is directly loaded into a tramcar through a coal-water separating device, pulverized coal of the current shift can be directly carried away, cost input is reduced, and the on-site quality standardization level is improved.

Description

technical field [0001] The invention belongs to the field of coal mining, in particular to a gas control method integrating drilling, flushing, screening and transportation. Background technique [0002] Coal is the main energy source that my country's economic development and people's lives rely on. For a long period of time in the future, coal's status as my country's main energy source will not change; in order to meet my country's coal demand, my country will develop some coal bases in an orderly manner in the future , build a number of modern mines. However, from a large number of mine project construction practices in the past in my country, it is not difficult to find that projects that fail to meet the expected goals are common, and have some adverse social and environmental impacts. This has a lot to do with the early decision-making and design of mine construction projects in my country. In order to achieve the best economic benefits of coal mine production and min...

Due to the defects of some anti-reflection technologies and process methods, the effect of many technical measures is not ideal

Patent CN201610263144.5 discloses a method of caving top-coal in weakened hard coal seams based on carbon dioxide blasting, which uses carbon dioxide blasting to weaken the hard top-coal, so that the top-coal discharge rate is increased by 20%-30% compared with that before roof fracturing, However, the drilling at the roof between the two hydraulic support beams near the coal wall has a great impact on the production of the working face
