Abstract

The invention provides a coal fire exploration method based on ground crack and temperature, which comprises the following steps of: exploring and monitoring the ground crack and the temperature of a predetermined area, and acquiring underground coal fire information of the predetermined area according to exploration results and monitoring results of the crack and the temperature. Compared with the prior art, the coal fire exploration method has the following beneficial effects that: ground cracks of a coal mined-out area and a fire area are explored at the same time, and therefore, a coal fire exploration and measurement evidence is provided for the treatment of the fire area, and evaluation or coal fire prediction and forecasting information is provided for control and advanced treatment of coal fire in the mined-out area. The coal fire exploration method has higher mathematic accuracy of exploration result compared with the coal fire exploration of the remote sensing technology, and more direct and more reliable coal fire information compared with the geophysical exploration technology.

Description

technical field [0001] The invention relates to a coal fire exploration method based on surface fissures and temperature. Background technique [0002] According to the "Code for Coal Field Fire Extinguishment" promulgated by the Environmental Protection Department of the former Ministry of Energy in 1992, the natural electric field method, magnetic method, infrared temperature measurement and drilling are the detection techniques specified for coal field fires. Since the 1980s, with the coalfield fire areas in Xinjiang and Ningxia. With the emergence of many coal mine fields such as Inner Mongolia, detection technologies such as aerospace remote sensing, thermal infrared imaging, isotope radon measurement, and geological radar have been gradually introduced into coal mine field fire exploration, making China's coal mine fire exploration technology begin to diversify and serialize direction development. [0003] In the past, whether in Xinjiang, Ningxia, Inner Mongolia or ...
