Good news - GSAI Geophysics won the first prize of

From January 19, 2024 to January 21, 2024, the first China Green Mine International Annual Meeting with the theme of "Convergence, Wisdom and Green Future of mining" hosted by Zhongguancun Green Mine Industry Alliance and China Enfei Engineering Technology Co., Ltd. was successfully held in Beijing. The annual meeting is an important event organized by the China Mining Association to promote the development and sustainable development of green mines.

At the beginning of the New Year, in this international academic event hosted by Zhongguancun Green Mine Industry Alliance, many excellent scientific and technological innovation achievements and outstanding talents were displayed and commended, and GSAI was invited to participate as one of the representatives of mining enterprises. Among them, the project "Research and Application of Regional Coal fire Comprehensive detection Technology based on spread spectrum IP", which was declared by GSAI, stood out among many projects and won the first prize of the "National 2023 Green Mine Science and Technology Progress Award". This award further highlights the leading position of Chinese enterprises in sustainable development and green mining, and also marks the breakthrough progress made by GSAI in sustainable development and environmental protection, and is an affirmation of its outstanding achievements in the field of mining, positive contribution to green development, technological innovation and sustainable development.

This project studies the regional coal fire comprehensive detection technology based on spread spectrum IP, and proposes the spread spectrum IP controllable emission and weak signal receiving technology based on pseudo-random m sequence electrical signals, so as to realize the synchronous generation and transmission of a variety of spread spectrum signals and improve the anti-interference ability. Based on theoretical analysis and model abnormal response characteristic analysis, through the study of spontaneous potential anomaly, excitation polarization characteristic and resistivity abnormal response rule in coal fire area, combined with typical coal fire area detection experiment and drilling verification, the fine evaluation system of array spread spectrum IP exploration area is established to provide high efficiency, high precision and low cost detection means for regional coal fire detection. Finally, a set of technical system suitable for regional coal fire detection is proposed to provide a strong technical guarantee for solving regional security, economic development and environmental pollution hazards.

Application field: Coal mine safety, green mine field.

Application: At present, it has been typical applied in spontaneous combustion coal mines in Xinjiang and northern Shaanxi. Through surface detection, the scope of underground coal fire area has been identified and the burning stage of coal fire has been identified. Through drilling verification, the temperature and gas measurement results of drilling are consistent with the conclusions of geophysical exploration.
