Shaanxi Yanchang Petroleum Balasu Coal Industry Co., Ltd. sent a thank you letter to China Coal Science Group Xi'an Research Institute Co., Ltd., congratulating the successful application of the "directional long drilling + conventional short drilling" segmented fracturing comprehensive three-dimensional advance regional governance technology in Balasu Coal Mine, which was independently developed by the mine pressure disaster prevention and control team of the Xi'an Research Institute for its successful application of the "directional long drilling + conventional short drilling" segmented fracturing comprehensive three-dimensional advance regional governance technology in Balasu Coal Mine. The balasu coal mine is an infrastructure mine. The upper part of the coal seam of its first mining face has multiple thick and thin sandstone layers and hard top plates, which are characterized by high strength, good integrity and strong self-supporting ability. During the initial mining period of the working face, the upper roof plate cannot collapse in time. The rear goaf area is prone to produce large-area overhangs. When it collapses, it is very easy to cause safety hazards such as " hurricane , bracket crushing to death" and other strong ore-pressure power disasters. To solve the above problems, the mine-pressure disaster prevention and control team of the Geological Gas Institute of Xi'an Research Institute is based on the actual situation on the spot, focusing on the governance goals, focusing on key issues, and targeting the comprehensive three-dimensional advance regional governance technology of segmented fracturing to the first mining work surface. During the critical period of construction, the leaders of the Geological Gas Institute visited the site many times to guide the overall deployment, implement safety responsibilities, and optimize resource allocation; during the construction period, the mine pressure disaster prevention and control team strictly controlled all links, flexibly adopted parallel operation methods, and completed the stage construction tasks with excellent professional qualities with high standards and high quality.
