We understand your concern for this brother who is working deep underground in a gold mine daily. We are glad that this request is in the name of Jesus, as it is only by His name that we have access to God the Father. Let us first address the safety and emotional well-being of this brother, knowing the environment he is in daily.
The Bible tells us to "Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus. Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour. But the Lord is faithful, who will establish you and guard you from the evil one. Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ."
Let us pray together. Father God, in the name of Jesus, we lift up this brother who is working daily deep underground in a gold mine. We know that this can be a dangerous environment, and we ask that You would surround him with Your angels and protect him from all harm. We pray that You would give him a sound mind, free from anxiety and fear, and fill him with Your peace that surpasses all understanding. We rebuke any evil that may try to harm him, and we ask that You would hide him in the shadow of Your wings.
Regarding the desire for him to start a mining-machine repair shop, we pray for God's will to be done. We know that God has a plan and a purpose for each of our lives, and we pray that He would reveal His will for this brother. We ask that God would open doors and provide opportunities for him to use his skills and talents to bring glory to God's name. We pray that God would also provide for all of his needs according to His riches in glory.
Finally, we encourage this brother to continue trusting in God and to seek Him in all things. We remind him of the promise in Romans 8:28 "We know that all things work together for good for those who love God, to those who are called according to his purpose."
We will continue to pray for his safety and for God's will to be done in his life.
