Abstract
The invention provides a method for detecting a coal field fire district distribution range, which is applicable to detection of coal field fire distribution ranges and development degree. According to the characteristic that coal field fire often happens in a coal petrography scattering area, a geological radar and a transient electromagnetic instrument detect electromagnetic wave amplitudes and secondary induction electromagnetic fields in a detection area, and a distribution range of the coal petrography scattering area in the detection area is defined. Gas measurement drill hole is constructed in the defined coal petrography scattering area in the detection area, gas in the drill hole is sampled, and compositions and concentrations of carbon monoxide, acetylene and ethylene in a gas sample is analyzed. A gas concentration distribution contour map is developed according to analysis results of the gas sample, the area with low concentration is the edge of the fire district, and the area with high concentration is the area with serious fire district development degree. By means of pre-detection of the coal petrography scattering area, pertinence of the fire district detection drill hole is improved, construction amount of the detection drill hole is reduced, and detection cost is saved. The method for detecting the coal field fire district distribution range is simple and high in detection accuracy, and has wide practical applicability in the field of detection of the coal field fire district.
Description
Technical field
The present invention relates to a kind of method of surveying coalfield fire district's distribution scope, be particularly useful for the detection of coalfield fire distribution range and development degree.
Background technology
There is a large amount of fire districts, coalfield in provinces (autonomous region) such as Xinjiang of China, the Inner Mongol, Shanxi, Ningxia, Gansu, Qinghai.Non-renewable coal resources are not only directly burnt in the existence of a large amount of coalfields fire, also cause tens of times dull resource not exploit indirectly, and the safety in production in direct threats colliery and local ecologic environment and groundwater resource.According to incompletely statistics, China reaches 1,000 ten thousand t because of coal fire scaling loss coal amount every year, and economic loss surpasses 20,000,000,000.Be realizing the efficient improvement of coal fire, reduce the loss of resource and to the pollution of environment, is crucial to effective detection in fire district.
The method that is used for both at home and abroad surveying in fire district, coalfield mainly contains boring thermometry, magnetic method, survey radon method and remote sensing method etc.The boring thermometry adopts temperature in the temperature measuring device testing bore holes such as thermopair, infrared thermometer through behind fire district construction drill, differentiates the distribution and the development degree in fire district according to the height of borehole temperature; This method is a kind of the most directly method, but because the thermal conductivity of coal petrography is relatively poor, for realizing more accurately surveying of fire district, needs at the intensive construction drill of whole detecting area (general pitch-row is less than 10m), and its workload is big, and cost is high; Magnetic method is drawn a circle to approve the Huo Qu border through the thermoremanent magnetism of surveying the burnt rock generation of fire district; But burnt rock generally only could produce remarkable thermoremanent magnetism after temperature is higher than 400 ℃; Because the thermoremanent magnetism of its generation is lower, cause detection accuracy relatively poor for the zone below 400 ℃; Therefore, this method can't satisfy 400 ℃ of following area detection requirements.Survey the radon method through the detection of detecting area radon element being differentiated the distribution situation in fire district, coalfield; Big fire district development degree is serious more more to think the concentration of radon element; But the influence that how much receives detecting area zone thickness, water cut, cranny development degree etc. of radon element is bigger in the actual detection process, causes this method detection accuracy lower; The remote sensing method is applicable to that the face of land has the obviously unusual fire district of temperature to survey, and is not suitable for surface temperature and manifests the district's detection of unconspicuous fire.
