Embodiment

[0033] According to its own conditions, through the continuous practice and summary of the bottom pumping roadway, a set of high-pressure hydraulic drilling, flushing, screening and transportation integration (7+1 mode) process for the bottom pumping roadway is explored, such as figure 1 Shown:

[0034] 1. High-pressure hydraulic punching pump station: Two sets of high-pressure hydraulic punching pumps are installed at the hydraulic punching site of 3205 bottom pumping alley, one for use and one for standby, which can provide water source with a pressure of 31.5MPa and a flow rate of 200L / min for high-pressure hydraulic punching. The water supply pipeline is φ32mm; and a water meter is installed at the water outlet of the pump station, which can record the amount of water required for flushing coal in each borehole. After the coal is seen in the drilling construction, the hydraulic punching pump is turned on, and the hydraulic punching is kept between 8-10Mpa. The punching pre...

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...
