不同煤体结构类型煤分层视电阻率值的测试

Measurement of apparent resistivity value for coal slices of different seam structures

利用DZ-ⅡA型防爆数字直流电法仪在淮南矿区井下对不同煤体结构类型的煤分层进行了 30组视电阻率值的煤壁测试。根据测试结果认为, 利用视电阻率仅能将不同煤体结构区分为硬煤和构造软煤两大类, 而测试结果有助于提高对不同煤体结构类型煤的电性差异的认识和相关物探资料解释的精度, 推动构造软煤非接触性探测工作的开展。

With the DZ-II A flame proof digital AC electric method meter, coal wall tests with 30 group apparent resistivity were conducted in coal slices with different coal structure in Huainan underground mining area. According to the test and measured results, it was hold that the apparent resistivity could not only classify the different coal structure area into tow classifications, hard coal and soft coal, but the results could be favorable to improve the identification of the electricity differential for different coal structure seam and the accuracy to explain the related exploration information, which could promote the development of the non contact exploration of the soft coal structure.
