Area of Science:

• Engineering
• Optical Communications
• Mining Technology

Background:

• Underground mining requires robust wireless communication systems.
• Visible Light Communication (VLC) is a viable alternative to radio-frequency links in mines.
• Existing VLC models for underground mines (UM-VLC) do not fully account for environmental factors like dust scattering.

Purpose of the Study:

• To develop and validate a realistic dust particle distribution model for UM-VLC systems.
• To analyze the impact of dust scattering on optical communication performance in underground mines.
• To enhance the accuracy of UM-VLC channel modeling.

Main Methods:

• Analytical derivation of a hemispherical 3D dust particle distribution model.
• Integration of the dust model into a UM-VLC channel model.
• Performance evaluation using numerical simulations based on the IEEE 802.1.5.7 standard.
• Analysis of key performance metrics: CIR, received power, SNR, RMS delay spread, and BER.

Main Results:

• The proposed hemispherical dust model provides a more accurate and realistic representation of scattering in UM environments.
• Increased dust particle concentration significantly degrades UM-VLC system performance.
• The model accurately predicts the negative impact of dust on communication metrics.

Conclusions:

• The hemispherical dust distribution model is crucial for realistic UM-VLC system design and performance prediction.
• Effective dust mitigation strategies are necessary to ensure reliable optical communication in underground mines.
• This research contributes to the advancement of wireless communication technologies for hazardous industrial settings.
