Embodiment Construction

[0055] like Figure 1-9 As shown, the coal seam heating and pulverized coal removal method of the present invention comprises the following steps:

[0056] Step 1. The length of the coal seam to be thermally mined is L, and the ground control center 1, the generator 2 and the ground reeling car 3 are placed on the ground above the coal seam. The ground reeling car 3 is provided with an intelligent cable winch 4. The cable winch 4 is wound with a high temperature resistant tensile cable 5, and the outlet end of the smart cable winch 4 is provided with a first tension sensor 6; after assembling n groups of hollow pipeline robot groups, one end of the high temperature resistant tensile cable 5 is connected to the generator 2 The other end of the high temperature resistant tensile cable 5 is connected to the rearmost hollow pipeline robot group; the intelligent cable winch 4, the first tension sensor 6, the generator 2 and all the hollow pipeline robot groups pass through the cont...

Abstract

The invention discloses a coal seam heating and pulverized coal removing method. The method comprises the following steps that firstly, the length of a coal seam to be subjected to thermal recovery isL, a ground control center, a generator and a ground wire winding vehicle are arranged on the ground above the coal seam, an intelligent cable winch is arranged on the ground wire winding vehicle, ahigh-temperature-resistant tensile cable is wound around the intelligent cable winch, and a first tension sensor is arranged at the wire outlet end of the intelligent cable winch; and n hollow pipeline robot groups are assembled, one end of the high-temperature-resistant tensile cable is connected with the generator, and the other end of the high-temperature-resistant tensile cable is connected with the rearmost hollow pipeline robot group. In conclusion, the method is high in automation degree, convenient to operate and good in pulverized coal removing effect, and the coalbed methane mining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of coalbed methane exploitation, and particularly relates to a method for heating a coalbed and removing pulverized coal. Background technique [0002] Coalbed methane refers to the hydrocarbon gas stored in the coal seam with methane as the main component, mainly adsorbed on the surface of the coal matrix particles, partly free in the coal pores or dissolved in the coal seam water. It is an associated mineral resource of coal and is an unconventional Natural gas is a clean, high-quality energy and chemical raw material that has risen internationally in the past decade or two. Due to the generally low permeability of coal seams in my country, the methods and effects of gas drainage are greatly limited. Therefore, how to improve the permeability of coal seams and then achieve the purpose of strengthening gas drainage is an important problem faced by the coal industry. Experts at home and abroad have put for...
