摘要

水力压裂技术是改变煤岩结构的有效手段，是解决煤矿技术难题的关键。该技术不仅可以改变煤岩体结构，降低硬顶板压力，降低煤尘浓度，保护工作环境，增加自然点火周期，避免火灾事故，而且可以防止任何残余物质在开挖过程中污染地下水和土壤。本文首先通过数值模拟研究了注水参数和裂缝倾角对水力压裂的影响，然后对硬顶板进行了水力压裂现场试验。结果表明，该方法的开裂效果明显，降低了顶板硬压和煤尘浓度。

Hydraulic Fracturing Technology and Environmental Protection

Hydraulic fracturing technology is an effective means of changing the structure of coal and rock, which is a key issue in solving the technical problem of coal mine. The technology can not only change the structure of the coal and rock mass, reduce the pressure on the hard roof, reduce the concentration of coal dust, protect the working environment, increase the natural ignition cycle, and avoid fire accidents, but can also prevent any residual material from polluting the groundwater and soil during excavation. In this paper, the effects of the water injection parameters and fracture inclination angle on hydraulic fracturing are firstly studied by numerical simulation, before hydraulic fracturing on the hard roof is subjected to a field test. The results show that the cracking effect is obvious, the hard roof pressure and coal dust concentration are reduced.

期刊介绍： The international Journal of Residuals Science & Technology (JRST) is a blind-refereed quarterly devoted to conscientious analysis and commentary regarding significant environmental sciences-oriented research and technical management of residuals in the environment. The journal provides a forum for scientific investigations addressing contamination within environmental media of air, water, soil, and biota and also offers studies exploring source, fate, transport, and ecological effects of environmental contamination.
