        <p>Для очистной выемки мощных пологих пластов предложена камерно-щитовая система с применением передвижных оградительных щитов. Производственные испытания такой системы (1959 г.) со щитом ЛГНК-1 подтвердили высокую эффективность и работоспособность передвижной крепи оградительного типа.</p>
